Hello folks.

I have made some X userinterface, using the X-toolkit(X11R2) for
a program which makes some analysis(unimportant here) on some files.
However the analysis is invoked by pushing a command-button and it
can take quite some time(several minutes) before the analysis is
through.
What I want to do is to make the analysis run as a parallel process
so that the user can make other things(maybe kill the analysis
clicking another button) during the analysis. I have made several
fork experiments, but I always(of course) get a copy of the whole
widget tree, which I certainly don't need or want.

My question is:

Are there some way to invoke background processes still using X to
control everything, but without getting a copy of the widgets ?
