    Description

      OSP can create a lot of commit callbacks to track changes to OST.

      also, due to current tracking mechanism, we allocate 732 in 3 chunks for every thandle and release up on commit. at 10K transactions/sec and 5s commit interval it gives ~35MB consumed. we can get rid of this.
