Jukka Zitting resolved OAK-1780.
--------------------------------
Resolution: Fixed
Fix Version/s: 1.0
Let's stick with the initial approach (precomputed segment graph per tar file)
for 1.0 and use followup issues for further improvements. I merged the change
to the 1.0 branch in revision 1592571. Resolving as fixed.

> Especially on non-SSD hard drives the TarMK cleanup can be quite expensive
> given the way it traverses the segment graph by stepping backwards through
> the tar files. We could considerably speed up the operation by keeping the
> precompiled graph of all segments within a tar file along with the index that
> stores the segment locations.
