The compute intensive code is a single piece of code (which I wrote),
and is shared with some command line apps, so is difficult to break into
short pieces and insert specific gtk stuff into. It would appear then
that threading would seem to be the solution. Todd Fisher has send an
example of using gthreads, and I will have a look at it this morning.

Best regards
