1) Has anyone seen this behavior before? If so, do you remember which
functions may be causing it (hg vs git speed under cygwin maybe?)

I pull it out of the prompt function
Anytime you have to call an external process, you pay a multiplied
penalty on cygwin -- 1st linux process spawning, while costly, are
less than Windows, and 2) cygwin has to emulate the posix semantics
on windows -- to which it is not friendly. If you could somehow cache
recent data in data struct and only updated ever 10 minutes with a
live call, that might help...?
