Since v1.6.0.2~13^2~ the completion of a thin pack uses sha1write() for
its ability to compute a SHA1 on the written data.  This also provides
data buffering which, along with commit 92392b4a45, will confuse pread()
whenever an appended object is 1) freed due to memory pressure because
of the depth-first delta processing, and 2) needed again because it has
many delta children, and 3) its data is still buffered by sha1write().

BTW, I run into complications trying to test the fix on Shawn's
master: conflicts,
and my trivial resolution wasn't good enough.

Huh.

Color me confused.  What the heck was the base version?

Near as I can tell Nico wrote this fix against a8032d12 (sha1write:
don't copy full sized buffers).  This is in Junio's master.

But the changes conflict with what is in Junio's maint.  So the
patch doesn't apply cleanly due to the sha1flush function's
signature changing.

And the changes conflict with 9126f009 (fix openssl headers
conflicting with custom SHA1 implementations), which is in my
master, and was written by Nico.

;-)

Anyway, its merged now.
