However I believe that what Gerald is talking about is using threads
for asyncronously executing upgrades.

I do not think that the very linking to the thread libraries causes
performance degradation.

If on a single processor you must continiuously switch contexts
between the main thread and the redraw one that causes a significant
overhead.

However, wouldn't be better just fork the upgrade agent?

yes.

we used to have 2 threads in the old ethereal for a short period.

one thread for the main application and a second thread that was
dedicated to only update/redraw teh statistics taps once every few
seconds.

this did cause a quite significant degradation in performance/speed of
ethereal which is why it was removed :-(
