      Description

      A unified scheduling module would consolidate logic around what operations get dispatched in parallel with other operations (fsync+lock and reads, e.g.), could ultimately manage resources (limit iops per individual user op, or disk space dedicated to external sorts at once), and more.

      TODO: Fill out the description w/ a fuller design proposal.
