Luke,

Define "hung"?  100% CPU?  0% CPU?  What was on the screen at the time?
Did setup react to Windows events (i.e., could you cancel it)?  Would you
be willing to try a debug snapshot of setup, attach to it with gdb when it
hangs, and post a backtrace for each thread?

Also, ISTR a patch that retried replacing in-use files after giving the
user a chance to exit all of his Cygwin processes, but don't remember if
it ever got applied.  Maybe it was only a discussion, not a patch...
