=head1 SYNOPSIS
+ NOTE: As of the 5.8.0 release, fork() emulation has considerably
+ matured. However, there are still a few known bugs and differences
+ from real fork() that might affect you. See the "BUGS" and
+ "CAVEATS AND LIMITATIONS" sections below.
+
Perl provides a fork() keyword that corresponds to the Unix system call
of the same name. On most Unix-like platforms where the fork() system
call is available, Perl's fork() simply calls it.
=item *
+In certain cases, the OS-level handles created by the pipe(), socket(),
+and accept() operators are apparently not duplicated accurately in
+pseudo-processes. This only happens in some situations, but where it
+does happen, it may result in deadlocks between the read and write ends
+of pipe handles, or inability to send or receive data across socket
+handles.
