: comparison of exception classes in a rescue clause
Changed to use Module#=== for comparing $! with the exception
class specified in each rescue clause.
As the previous behavior was to use kind_of?, the effect is limited
to the SystemCallError case. SystemCallError.=== has been newly
defined to return true when the two have the same errno. With this
change, SystemCallError's with the same errno, such as Errno::EAGAIN
and Errno::EWOULDBLOCK, can both be rescued by listing just one of
them.
