[ale] ssh stalls (OT - cygwin)

[David Corbin]

We're using ssh from cygwin in an automated upgrade process for a bunch of 
Windows boxes. In tests, some really wierd stuff is happening.  We've 
remotely execute a command via ssh, and that command executes and runs fine.  

However, the ssh client does not return for almost exactly two hours (+/- 30 
seconds).  This doesn't happen EVERY time we do it, but it's often enough to 
be a big concern to us.

Given all the smart people here, I though I'd see if anyone has any ideas.  I 
have not yet turned up the debug level of sshd, but I will.
