I can easily reproduce this with a self-built DLL from 20060827, but 
only if I invoke file1.sh from within bash. If I run "bash file1.sh" 
from a CMD shell, it works fine.

Also (perhaps not surprisingly), if I add a wait at the end of file1.sh, 
it runs fine until I Ctrl-C out of file1. Then, it will eventually hang 
again.

Once it hung, I tried to kill the process bash process running file2.sh.

% handle file2

kill: couldn't kill pid 1100, 5

I can kill Windows pid 5052 using the Windows Task Manager.
