Thanks.  There's no great urgency on my part, I just need it for after Emacs
release.  It's about to go to pretest but this will probably be a drawn out
process if the two and a half year feature freeze is anything to go by.

OK, I'll try that.

In the meantime, I've noticed that the patch forces GDB to run synchronously.
In target.c, update_current_target must be made to inherit async methods again.
This means that server-run.exp still doesn't work (and probably any test which
changes to a synchronous target).  I'll include this when I submit a cleaned up
patch.
