This should be fixed in tonight's snapshot. Thanks for reporting it.
This is a manifestation of a problem that has been plaguing me since
April. This easily reproducible test case allowed me to track down
a problem which was causing random handles to be closed.
I did notice while debugging this that strace -f hangs on Windows 95.
If anyone has any insight into why, I'd be interested in hearing about
it.
