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). Maybe that's enough
