Edit done May 16, 2007.
Ryan and Tobais, sorry but I just saw your comments. I could not figure out how to reply
with a comment (comment period being closed and I didn't want to mess with the
settings too much) so I'm editting the blog to respond.
The line "CMS-concurrent-abortable-preclean" does not indicate a problem. The "abortable"
only indicates that the current phase (precleaning) can be interrupted in order to start
the next phase.
Yes, the UseParallelOldGC does imply UseParallelGC.
