Please do not use os.fork() on OS X. CoreFoundations do not support daemonization via fork(). ​More information about this provided by Apple

Please see the resulting error message:

The process has forked and you cannot use this CoreFoundation functionality safely. You MUST exec().
Break on __THE_PROCESS_HAS_FORKED_AND_YOU_CANNOT_USE_THIS_COREFOUNDATION_FUNCTIONALITY___YOU_MUST_EXEC__() to debug.

The binary is then being stopped by SIGABRT.

Thanks for the info! Currently we do not have any Macs to develop on, so this may not be fixed for a while.
