[Buildbot-devel] Database is locked exceptions in 0.8.5

Well, we're just running 0.8.5 with the default sqlite options which I 
believe enables WAL - and I'm seeing this line in twistd.log when 
buildbot starts:

2011-10-05 12:43:26+1300 [-] setting database journal mode to 'wal'

So hopefully that confirms it's working.

Is there anything else I should check, or other configuration needed?
