Run the supplied function in the context of the domain, implicitly
binding all event emitters, timers, and lowlevel requests that are
created in that context. Optionally, arguments can be passed to

This is the most basic way to use a domain.
Example:

console.error('Caught error!', er);
});

Once `dispose` has been called, the domain will no longer be used by callbacks
bound into the domain via `run`, `bind`, or `intercept`, and a `'dispose'` event
is emitted.
### domain.enter()
The `enter` method is plumbing used by the `run`, `bind`, and `intercept`
methods to set the active domain. It sets `domain.active` and `process.domain`
to the domain, and implicitly pushes the domain onto the domain stack managed
by the domain module (see [`domain.exit()`][] for details on the domain stack). The
call to `enter` delimits the beginning of a chain of asynchronous calls and I/O
operations bound to a domain.
Calling `enter` changes only the active domain, and does not alter the domain
itself. `enter` and `exit` can be called an arbitrary number of times on a
single domain.
If the domain on which `enter` is called has been disposed, `enter` will return
without setting the domain.
### domain.exit()
The `exit` method exits the current domain, popping it off the domain stack.
Any time execution is going to switch to the context of a different chain of
asynchronous calls, it's important to ensure that the current domain is exited.
The call to `exit` delimits either the end of or an interruption to the chain

* {Object}
The `process.env` property returns an object containing the user environment.
See environ(7).
An example of this object looks like:
```js
{
TERM: 'xterm-256color',
SHELL: '/usr/local/bin/bash',
USER: 'maciej',
PATH: '~/.bin/:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin',

EDITOR: 'vim',
SHLVL: '1',
HOME: '/Users/maciej',
LOGNAME: 'maciej',
_: '/usr/local/bin/node'
}
```
It is possible to modify this object, but such modifications will not be
reflected outside the Node.js process. In other words, the following example
would not work:
```console
$ node -e 'process.env.foo = "bar"' && echo $foo
```
While the following will:
```js
process.env.foo = 'bar';
console.log(process.env.foo);
```
Assigning a property on `process.env` will implicitly convert the value
to a string.
Example:
```js
process.env.test = null;
console.log(process.env.test);
// => 'null'
process.env.test = undefined;
console.log(process.env.test);
// => 'undefined'
```
Use `delete` to delete a property from `process.env`.
Example:
```js
process.env.TEST = 1;
delete process.env.TEST;
console.log(process.env.TEST);
// => undefined
```
On Windows operating systems, environment variables are case-insensitive.
Example:
```js
process.env.TEST = 1;
console.log(process.env.test);
// => 1

console.log(process.env.foo);
```
Assigning a property on `process.env` will implicitly convert the value
to a string.
Example:
```js
process.env.test = null;
console.log(process.env.test);
// => 'null'
process.env.test = undefined;
console.log(process.env.test);
// => 'undefined'
```
Use `delete` to delete a property from `process.env`.
Example:
```js
process.env.TEST = 1;
delete process.env.TEST;
console.log(process.env.TEST);
// => undefined
```
On Windows operating systems, environment variables are case-insensitive.
Example:
```js
process.env.TEST = 1;
console.log(process.env.test);
// => 1
```

option is enabled or not. This makes V8 overwrite heap garbage with a bit

continuously touches all heap pages and that makes them less likely to get
swapped out by the operating system.
