Hi Greg,

Some data and a few questions: 1. The failure on FreeBSD is not the same as on OS X. I built 6.4.2 from cvs on FreeBSD 6.1, and ran the ghc-regress tests. The tests took a long time to run (about 14 hours on a dual Xeon 2.8 GHz with 2 GB of memory). Towards the end of the tests, there were about 30 "timeout" processes running, apparently doing nothing but consuming cpu cycles.
Ok, this is certainly a problem with forkOS in the threaded RTS in 6.4.2 on FreeBSD. I probably need to get access to a FreeBSD box to fix this myself, the code is pretty delicate (and sadly it has completely changed in 6.6, too).
The same problem exists on Mac Intel. -- http://wagerlabs.com/
