Partial support for deadlock detection in the threaded/SMP RTS. The idea is to wait until a complete time slice has gone by without running any Haskell code, and then try doing a GC to detect deadlocked threads. This kind of works: but we can only wake up a worker thread from the signal handler if there's another worker running - we can't wake up the current thread, it seems.
