OK, this shows why it is slow.  The algorithm in add_findex is only efficient
when called with consecutive index values (the third number printed).

The code for "restore all" in 2.4.4 doesn't do that, so it can take a very
long time to complete.  This was fixed in later version, so I think the best
solution is to upgrade Bacula.
