This appears to be causing random problems for me where bitbake will
timeout attempting to access the PR database, my hunch is that it's
blocking on disk I/O.  Are there any tricks we can do with sqlite to reduce
the overhead of committing? (assuming that sqlite isn't causing a full
filesystem sync).
