Simon,
How is this easier than just calling threadDelay?
Ideally, I would be looking for something like reading from a TVar
with a timeout. So that you either get a Nothing (timeout) or the
value from the TVar. Can I implement it using the GHC timeout thread?
Thanks, Joel

Interestingly, GHC already has a timeout thread - the I/O manager
thread
handles threadDelay too. It wouldn't be too hard to adapt it to do
STM
timeouts too, with a function like
registerTimeout :: Int -> STM (TVar Bool)
and you wait for your timeout by waiting for the TVar to contain True.
