"Future::IO::ImplBase" − base class for "Future::IO" implementations
This package provides a few utility methods that may help writing actual Future::IO implementation classes. It is entirely optional; implementations are not required to use it.
__PACKAGE__−>APPLY;
Attempts to set the value of the $Future::IO::IMPL variable to the name of the calling package.
These methods are provided based on lower−level functionallity that the implementing class should provide.
Implemented by wrapping "ready_for_read", as "sysread" uses.
Implemented by wrapping "sleep".
Implemented by wrapping "ready_for_write", as "syswrite" uses.

Requires a lower−level method
$f = $class−>ready_for_read( $fh );
which should return a Future that completes when the given filehandle may be ready for reading.
