// Test sending and receiving a file descriptor.
//
// This test is pretty complex. It ends up spawning test/fixtures/recvfd.js
// as a child to test desired behavior. What happens is
//
// 1. Create an in-memory pipe via pipe(2). These two file descriptors
// are not visible to any other process, and so make a good test-case
// for sharing.
// 2. Create a a UNIX socket at SOCK_PATH. When a client connects to this
// path, they are sent the write end of the pipe from above.
// 3. The client is sent n JSON representations of the DATA variable, each
// with a different ordinal. We send these delimited by '\n' strings
// so that the receiving end can avoid any coalescing that happens
// due to the stream nature of the socket (e.g. '{}{}' is not a valid
// JSON string).
// 4. The child process receives file descriptors and JSON blobs and,
// whenever it has at least one of each, writes a modified JSON blob
// to the FD. The blob is modified to include the child's process ID.
// 5. Once the child process has sent n responses, it closes the write end
// of the pipe, which signals to the parent that there is no more data
// coming.
// 6. The parent listens to the read end of the pipe, accumulating JSON
// blobs (again, delimited by '\n') and verifying that a) the 'pid'
// attribute belongs to the child and b) the 'ord' field has not been
// seen in a response yet. This is intended to ensure that all blobs
// sent out have been relayed back to us.
