This commit was SVN r15924.
The following SVN revisions from the original message are invalid or
inconsistent and therefore were not cross-referenced:
r15795
r15921
stage fairly confident that
- it works in most scenarious (with symmetric hierarchies, with asymmetric
hierarchies, wihout hierarchies - it just removes itself)
- it does not create too many problems (I am not aware of any at least)
- it does not slow down startup anymore dramatically (thanks to the fixes of
Brian, Jeff, Tim and a significant reduction in the number of collective
operations in the comm_query)
Any feedback is highly welcome.
This commit was SVN r7868.
