OK.  I seem to recall these pack files are created with something like

	open
	write
	sync
	close
	rename

? 

Yes. We're trying to be _extremely_ safe and only do things that should 
work for everything.

This is just ext3 with data=writeback on a local laptop disk,
ubuntu's 2.6.24-21-generic.  Would it be any use trying to look more
closely at the pack in connection for any hints?

You still have the packfile that caused problems available somewhere? If 
so, absolutely yes. If you have the corrupt pack, please make it 
available.

(But with my git repo back I'm happy enough to just forget this for now
if there's not anything obvious to try.)

With the actual corrupt pack, we can make a fairly intelligent guess about 
exactly what the corruption was. Was it a flipped bit, or what? So if you 
have it, please do send it over.

OK!  It's in:

	http://www.citi.umich.edu/u/bfields/bad-pack/

I assume the .idx file isn't interesting, but it's there anyway in case.
