I think Linux (at least some kernel levels) has a serious problem with letting the main thread die w/o killing off the other threads in the process first. If you let the main thread exit before allowing the other threads to exit, you end up with a hosed process that doesn't go away. I presume this is a bug in the Linux pthread implementation... Bill
