Hi,

I ran today into the failure that this commit fixes:
...
FAIL: gdb.threads/watchthreads-reorder.exp: reorder1: continue to
breakpoint: break-at-exit (GDB internal error)
...
on the 8.3 branch.

My understanding from reading the rationale is that this is sufficiently
cornercase to not merit a backport, but perhaps someone thinks otherwise?

If we decide not to backport, we could perhaps mark this as as KFAIL in
the 8.3 branch?

Thanks,
- Tom
