Wilfred Spiegelenburg commented on YUNIKORN-1443:
-------------------------------------------------
You need to lock the partition to remove the expired applications. You do not
have access to the partition object from the application itself. You will thus
not be able to remove the application from the partition on expiration.
Fixing that causes circular dependencies when you try to do that the simple
way. Working around the circular dependency complicates the code and is far
more difficult to maintain than the code to kick off a cleanup thread once in a
while.
