Hmm... Could the allocation of large contiguous blocks also lock the system hard? For instance, I avoid starting the test suite on my XP workstation at work: it locks up hard every time. W2k works. The system has nothing unusual in it. Well, it has an antivirus program (which hopefully stopped working after a series of crashes, which is just as well), an NVidia card with native driver (which is broken in its own usual ways).
