Yes, we're seeing the same problem here. I've actually traced the
problem to a stack overflow in the select system call. However my
windows95 machine died before I could test my patch.

I'll send you an updated 'lwp.dll' file which has twice as much
stackspace reserved for the thread that calls select. Maybe it works,
maybe it won't.

The strangest thing is that Venus uses the same iomgr thread but doesn't
crash, whilst it is a much more complex program. (i.e. I would have
expected Venus to crash sooner than clog).
