Log:
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.
