[PATCH] dlfcn: do not mark dlopen/dlclose as leaf functions

This description doesn't track.  You meant to say "indirectly invoke".
The comments in the test case are clear enough, but this introduction
was misleading enough that I thought you might be wrong about something.

The comments at the top of the test sources are not in the canonical style.
Nowadays I think we are doing copyright notices on new test cases too.
Every new test case should use test-skeleton.c unless there's a big reason
that it cannot.

And, needs a BZ# filed as was already mentioned.


Thanks,
Roland
