Thanks for the strace.  That was weird.  Apparently the stack pointer was
completely messed up somehow.

I have made a couple of changes to the spawn call in the current .dll.

As I'm away from my desk (by about 3000 miles) I can't easily run your test
case.  If you could give this new .dll a shot and let me know how it works,
I'd appreciate it.  It's in the same location.
