Crud, ok. Keep us posted.

I'm testing with checkpoint/restart and the new libevent seems to be
messing up the checkpoints generated by BLCR. I'll be taking a look
at it over the next couple of days, but just thought I'd let people
know. Unfortunately I don't have any more details at the moment.

WHAT: Bring new version of libevent to the trunk.
WHY: Newer version, slightly better performance (lower overheads /
lighter weight), properly integrate the use of epoll and other
scalable fd monitoring mechanisms.
WHERE: 98% of the changes are in opal/event; there's a few changes to
configury and one change to the orted.
TIMEOUT: COB, Friday, 21 March 2008
DESCRIPTION:
George/UTK has done the bulk of the work to integrate a new version
of
libevent on the following tmp branch:
https://svn.open-mpi.org/svn/ompi/tmp-public/libevent-merge
** WE WOULD VERY MUCH APPRECIATE IF PEOPLE COULD MTT TEST THIS
BRANCH!
**
Cisco ran MTT on this branch on Friday and everything checked out
(i.e., no more failures than on the trunk). We just made a few more
minor changes today and I'm running MTT again now, but I'm not
expecting any new failures (MTT will take several hours). We would
like to bring the new libevent in over this upcoming weekend, but
would very much appreciate if others could test on their platforms
(Cisco tests mainly 64 bit RHEL4U4). This new libevent *should* be a
fairly side-effect free change, but it is possible that since we're
now using epoll and other scalable fd monitoring tools, we'll run
into
some unanticipated issues on some platforms.
Here's a consolidated diff if you want to see the changes:

2Flibevent-merge&old=17846&new_path=trunk&new=17842
Thanks.
