=head2 DTrace support

On platforms where DTrace is available it may be enabled by configuring
perl with -Dusedtrace. DTrace probes are available for subroutine entry
(sub-entry) and subroutine exit (sub-exit). Here's a simple D script
that uses them:

   perl$target:::sub-entry, perl$target:::sub-return {
     printf("%s %s (%s:%d)\n", probename == "sub-entry" ? "->" : "<-",
               copyinstr(arg0), copyinstr(arg1), arg2);
   }

Are there modules in core that are otherwise orphaned? I'm happy to  
pick some up and give 'em some love.
