Hey, catch fork/vfork is supported on OpenBSD too!  I'll submit a
follow-on diff once Daniel's gets committed ;).

Are you sure catch vfork works?  Nothing in inf-ptrace.c generates
TARGET_WAITKIND_VFORKED - looks like I searched for that instead of
..._FORKED.

Heh, it doesn't.  I rmember now that the vfork semantics made things a
little bit difficult, and that I didn't add support for it in the
kernel.
