Comment(by kazu-yamamoto):
I run the original test code (using System.Process) with GHC
7.0.2rc1/-threaded and checked the running echo daemon with "lsof". There
should be one kqueue socket and two pairs of pipe (which is used by
System.Event.Control). But there are not such file descriptors. So, I
guess kqueue.new fails after "daemonize".
