Re: 1.4.3 and svnserve/db45 transient testsuite failures

From: Blair Zajac <blair_at_orcaware.com>

Well, I would rather not count on that, as it sounds like the easy
answer (go check your memory, so I don't have to look for the hard
heisenbugs :) )

Seriously:

1) This is the same box I do all my previous svn builds on and it's
never had this issue.
2) It's in a nice managed server room.
3) It's used by 50 developers as a standard compile box.

Maybe we should just bookmark this and if other people see similar
results with db45, then we can look into it further.

Regards,
Blair
