    [darwin] package Monobjc as an experiment
    
    I have no idea if I want to use this, but it looks pretty complete and
    interesting. Basic testing shows some things working - GTK and the CFRunLoop
    seem to integrate nicely together, and I could get volume/mount notifications
    from NSWorkspace in GTK ... so that's one step closer to hardware support.
    
    This thing was a nightmare to build and integrate though. Jeesh.
