Hi Dmitry,

Sorry for the delay. I made a note to test this and promptly forgot about it
for several months :(.

In any case, it doesn't seem to help. I was able to get a crash on my first
attempt with this patch. Later attempts ran further, so it doesn't seem to make
it any worse either..

This was without native msvcrt. I'll try that next.
