Problem solved: timing issue. Problem in C land, not in Lisp.

I had to tweak the timeouts for the select() call a little to get
stable behaviour. I've never seen this before: different timings
on the same machine (I had factored in that there are different
runtime situations because the total set of processes obviously
varies over time) - but now I have seen that the Lisp runtime env
of that one process just acts a bit differently timewise. So I
made all my timeouts into variables I can tweak ... Easy. Now
that part runs as desired.

Duane fired a series of questions at me and I did get quite some
"there has to be a simple reason and a simple solution" kick from
those questions - in the end I saw what to do because Duane made me
look!

And it was not an Allegro CL related problem at all ... Thanks again
for a superb, directed, responsive support from Franz.

Frank
