That's a good question.
Sometimes waiting until it's hung is just a split second too late. But, if the problem doesn't creep in until after it's been running a long time, it probably isn't feasible to start the process with strace either. The problem has to be predictable and occur soon-ish. -- Mark D. Foster <[email protected]> http://mark.foster.cc/ | http://www.freegeekseattle.org/
