[Unison-hackers] [unison-users] unison.tmp files

[Benjamin Pierce]

I think the main issue with this partial fix will be that, if Unison  
is interrupted, then any temp files from this run will not be  
recognized as such and the next run will try to propagate them  
instead of deleting them.  This could be worked around using the  
"ignore" preference.
