Hi Jason,

It's not the way to go, unfortunately.

I guess it's actually a fault in Cygwin's mmap() implementation but I
don't see the cause so far.  I'd greatly appreciate if you could put some
effort into analyzing the problem.  Could you send a fragment of the
strace output grep'd for 'm\(un\)*map' in the meantime?  Perhaps I get an
idea by goggling into the debug output...
