Small clarification. The deadlock I see happens if one of the following
RTS setup is used [[BR]]
1. "+RTS -N2 -g1 -DS --install-handlers=no -RTS"[[BR]]
2. "+RTS -N1 -DS --install-handlers=no -RTS"[[BR]]
I observe the issue with slightly more complex program (using
createProcess from System.Process).
