Have a look at GHC.Conc.forkProcess
Interesting. How exactly does it work, by the way?
Trade secret ;) Simply drop the TSO pointers to all other threads from the queues so the RTS won't find them again (GC is a different issue).
Posix.runProcess really should use it I think.
No, it's better to be able to choose the way to handle this. Maybe add a flag to Posix.runProcess. But the whole GHC.Conc.forkProcess isn't finished, yet, anyway.
The signature of Posix.runProcess is not quite adequate though; one wants some control over the child thread. At a minimum, it would be nice to be able to kill it. ^^^^^^^^ process?
You still get the child's pid, so feel free to mess with it. -- plonk :: m a -> m () http://www-i2.informatik.rwth-aachen.de/stolz/ *** PGP *** S/MIME
