I can now reproduce this at will on both 1.8.0 and master.  Although it can certainly
be provoked by a small cache, that is not a requirement; my cache is large enough to
hold any of the pack files, and I am seeing 'bus error' while simply cloning a
relatively small OpenAFS repo.

The bus error is happening in kernel code due to an error on a page fault
for one of the pack files which git has mmap'd.

However, I don't yet know the root cause.  Even though I can reproduce this at will,
I'm having difficulties using systemtap to find out exactly what is wrong.

I'll keep you informed of my progress.
