Comment(by sanketr):
I can reproduce it consistently using the code below (only on 7.0.3, not
7.4.1 RC1):
{{{
import Control.Concurrent (forkIO, threadDelay)
main = forkIO $ threadDelay maxBound
}}}
{{{
$ ghc t.hs -threaded -rtsopts
$ ./t
t: ioManagerDie: write: Invalid argument
t: kevent: invalid argument (Invalid argument)
$ uname -a
