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

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
