Hmmm - I did try tracing the process and it looked like it was looping
on doing select/poll/gettime calls, it is hard for me to tell whether
this was part of the normal X event loop or if emacs is stuck
somewhere else.  Hmmm I just tried emacs on a plain ascii console and
that seems to behave itself.

Maybe - the laptop is not exactly the fastest machine about (it's a
P150 DEC HiNote Ultra II), I can try this on my server which has a bit
more grunt and see if I see the same problem.  At the moment I am
suspecting it is more a wierd emacs+X+coda interaction, perhaps there
is a race condition in there somewhere I am triggering.

20Mb max, I am using about 143Kbytes at the moment.
