I find this behaviour a little annoying. Sometimes I *want* the thread
to block indefinitely! I.e. I want it to block until it receives a
KillThread exception. Is there a better way to accomplish that without
waiting on an MVar which will never fill? As a workaround what I've
been doing lately is stashing another reference to the mvar somewhere
else (I'm guessing the trigger condition for
"BlockedIndefinitelyOnMVar" is "blocked and mvar refcount == 1").

I don't know if there's a way to disable it, but you can wrap all your spawned threads with an exception handler that catches BlockedIndefinitelyOnMVar and ignores it. If the thread blocks indefinitely, it's as good as dead, so there won't be any difference in behavior.
Cheers, Edward
