Test case

See the attached example code.

A loop running UnixSignal.WaitAny() is executed in a background thread.  The
loop terminates on SIGINT.  The main thread waits for return to be hit and then
calls Environment.Exit().  The application should then exit no matter the state
of the background thread.

Unfortunately, the runtime doesn't kill the background thread, and it continues
to block in UnixSignal.WaitAny().

Tested on 2.6 branch, updated 1/4/10.
