What platform is this?  index-pack failed to read using pread(),
but the error code in errno was 0 (success)?  Huh?

It turns out this is steaming from a short read; we asked for some
length of bytes but did not get that exact value.  That sounds like
the packfile is truncated.

Ohh - is this repository on NFS, or some other sort of network
filesystem?  Maybe the FS couldn't give us the entire pread request
in one shot...

I think the pread() in get_data_from_pack of index-pack is wrong,
it really should be looping until we fill the buffer in case the
OS doesn't fully satisfy our read request the first time.
