Okay, I'm looking through this trace in the hope of finding something.
The below looks suspicious, but I'm not sufficiently familiar with
either Git or Cygwin internals to know (a) whether this is a problem at
all or (b) if it is a problem, whether it's a symptom of an earlier
problem I haven't spotted on my brief skim.

I'm also curious about the difference between the MinGW32 version and
the Cygwin version.  Possibly it's barking up completely the wrong tree,
but what versions of each are you running?

In the hunt for a simple test case, is it just this repository that's
causing problems, or are others being difficult too?  Specifically, I'm
wondering about a trivial repository with only a handful of objects.

Do you know anything about that 300bdeb object? In particular, is it
particularly big or unusual in some other way?
