I can reproduce it, too.  However, I can not reproduce it on Windows
Server 2008 x64 so it seems a problem of the NT 5.2 kernel alone.
I tried debugging and changed a couple of places in the DLL as well
as in cygrunsrv trying to track it down.  The hang does not occur in
Cygwin code, afaics, but in OS code and changing related parts of the
custom console handling doesn't change anything.  That's all I can do
for now, sorry.
