Bleah, this seems to have broken sigtramp detection on HP-UX 10.20.
Problem is that if we go up one frame from the signal handler we end
up in the export stub for _sigreturn, and not _sigreturn itself.  The
export stub doesn't have the HP_UX_interrupt_marker bit set in the
unwind record.

Did you make this change to fix a specific problem?  If not I'd like
to add the strcmp() back in...

sigh, ok, please add the strcmp back (with a comment).
