Hello Simon,
with 6.12.1.20100313 the behaviour is worse: even when using $! in the appropiate lines (see [2] in my original message) the programs hangs quite often. Hence, 6.12.1 works better in this (special?) case.
Ok, I'll look into it, thanks for the report.
I reproduced the deadlock, and it looks like a new one: a lock order reversal between Schedule.c:checkBlackHoles() and RtsAPI.c:rts_unlock(). It turns out I've already fixed it in the HEAD as a side effect of some other improvements, so I'm going to try to bring those into the 6.12.2 branch. Cheers, Simon
