[PATCH v2 0/2] Retry attempts to acquire the packed-refs lock

This is a re-roll of [1]. The only change is the addition of a "wait"
in the test to avoid an unlikely race between the lockfile-removing
subprocess and the attempt by the outer layer of the test to delete
the test directory.

Thanks to Hannes, Stefan, and Peff for their comments about v1.
