I have roughly the same problem on Windows NT and Windows 95.  It is a real
pain when the entire machine hangs and you have to power cycle to continue.
This is obviously a Windows design bug but it is annoying that GDB exercises
it.

The only way I've found around this problem is to always let the debugged
process run to completion and to never use 'q' in gdb.  Always kill the
gdb process from another process or from the Task Manager.  If you can't
let the debugged process run to completion then you can kill it also.

This seems to work 80% of the time at least.
