* Add support for the IO manager thread on Windows
Fixes #637.
The implications of this change are:
- threadDelay on Windows no longer creates a new OS thread each time,
instead it communicates with the IO manager thread in the same way as
on Unix.
- deadlock detection now works the same way on Windows as on Unix; that
is the timer interrupt wakes up the IO manager thread, which causes
the scheduler to check for deadlock.
- Console events now get sent to the IO manager thread, in the same way as
signals do on Unix. This means that console events should behave more
reliably with -threaded on Windows.
All this applies only with -threaded. Without -threaded, the old
ConsoleEvent code is still used.
After some testing, this could be pushed to the 6.6 branch.
