I set annex.queuesize to 100, made 1000 files, and was able to reproduce
the hang.
A `git-annex smudge --update` process has open the `.git/annex/gitqueue.lck` file.
It is the only process with that lock file open. So it is in the process of trying to
flush the queued changes to the index that it is locking up.
I removed .git/hooks/post-checkout, and then after the `git-annex adjust`,
manually running `git-annex smudge --update` causes the same hang.
Debugging the git queue flush, it is hanging while running a FlushAction, specifically
restagePointerFileRunner.
And the hang occurs when restagePointerFiles calls
Database.Keys.Handle.closeDbHandle.
I suspect this bug may not be specific to `git-annex smudge --update` at all. It may be
that any time the git queue gets flushed with restagePointerFileRunner in the queue it
hangs like this. This needs further investigation.
