 =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.

+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
