[Unison-hackers] MacOSX Unison still crashing

[Benjamin Pierce]

I'm guessing this is the same as the intermittent crash I'm seeing in  
the OSX GUI, which is believed to be related to a race condition in  
the GUI.  (The text UI does not exhibit the problem for me, so using  
it is a workaround.)

Regards,

      - Benjamin
