+Perl can only use a vfork() that doesn't suffer from strict
+restrictions on calling functions or modifying global data in
+the child.  For example, glibc-2.1 contains such a vfork()
+that is unsuitable.  If your system provides a proper fork()
+call, chances are that you do NOT want perl to use vfork().
