Thanks again for doing all this, really appreciate it.
Well, we're closer....
The showstopper for us is still the flock() issue. We have Mathew Wilcox's patch from
2.5.52, which we have been applying to all recent kernels. The patch is in PLM as patch id
# 1061. The issue is in BugMe as bug #94 . 
Without proper flock() we cannot stop and restart the database, which means we can't run the test. 
We've tried applying Wilcox's flock patch to -mm1, but it's doesn't go clean, and frankly we're not smart enough
to do the merge by hand -  lock code scares us. 

We just tested 2.5.61 vanilla, and 2.5.61-mm1. 

The patch applies cleanly to stock 2.5.61, and we can cycle the database.
We can't run dbt2 on stock 2.5.61, because of the scheduler bug. 
We believe the scheduler fix in -mm1 will be the ticket, but we can't try
it because of the flock() issue. So we're wedged. 
Can someone smarter than us maybe do a merge? 

thanks,
cliffw
