It seems +that under heavy write load, when a new connection is made to the database, +SELECT can fail for a little while. Once one SELECT succeeds, that database +connection becomes solid, and won't fail any more (apparently). This makes +me think there might be some connection initialization steps that don't end +up finishing before the SELECT goes through in this situation. I should be +able to work around this problem by probing new connections for stability, +and probably will have to, since it'll be years before any bug fixed sqlite +is available everywhere. + +I also noticed that current git-annex incremental parallel fsck doesn't +really parallelize well; eg the processes do duplicate work. So, the +database branch is not really a regression in this area.
