I've picked up this patch (well, an updated version Daniel sent me) and
I intend to get it working and resubmitted.  I've got it mostly passing
the testsuite now (there were a couple of problems, with frames and
such).  The tracepoint test will fail until that bit is implemented,
which I don't see as a blocker; I'll try to do that bit as a separate
patch afterwards.

I'm still working on cleaning up some bogosities, etc. etc., so it will
be another day or two.
