I was unaware that linux currently uses lightweight process for multithreading. As far as I know in the past a pthreads library was used and a multithreaded program ran as a single process. >You will probably not be able to diagnose your problems 'from below' as you are >trying to do.

I was hoping for a temporary solution that would prevent the other sessions from dying should one have a problem.
