> In [1] has been described scenario of the race that makes possible a
> situation when information from metastore has been deleted and part of the
> index is still present in the storage.
> Actually, fix in [1] that has been done in slightly different way, however,
> it strongly decreases possibility of the race. Removal of the background task
> has been moved to beginning of the next checkpoint. It was done this way,
> because the problem was in case when node unexpectedly failed in the middle
> of next checkpoint and after restart task failed on check of deleted index
> metaPage. The check was done in [2].
> In current issue, we only move background task deletion at the end of the
> next checkpoint.
