[PATCH 0/2] midx: prevent against racily disappearing packs

[Taylor Blau <me@ttaylorr.com>]

Here are a couple of patches that Peff and I wrote after noticing a
problem where racily disappearing .idx files can cause a segfault. While
investigating, we fixed a related issue which is described and fixed in
the second patch.

(I'm a little behind in responding to review on the reachability
generation improvements patches, but had these in my backlog and they
seemed relatively easy to send and remove from my TODO list. So, here
they are :-).)

Thanks,
Taylor
