Thanks very much for bringing these to my attention.

I've fixed this in the current patches.

I haven't been able to reproduce this so far on my test machine. I got
bored after about 10 minutes ("passed: 119200000"). The machine remains
responsive and the test dies immediately on hitting C-c. I'll try it on
some other machines. It would help to know what kind of unusable (crashy,
leaky, wedgey?).


Thanks,
Roland
