Well, mail to probably won't reach me.  It's either or  Anyway, I committed an
NetBSD/amd64 port yesterday.  It doesn't do core-dumps yet, but I have
some pending changes that should make those work.  Backtraces through
signal trampolines are working AFAICT.  However, there is some strange
interaction between ptrace(2) and pending signals; in particular
SIGALRM.  If you try to single-step a program with a SIGALRM pending,
GDB doesn't see the SIGALRM and doesn't step either.  This smells like
a kernel bug to me.  Haven't looked into it yet though.
