Parsing Rewrite

BwAuthority, postgres, and the changes in #3679 provide the perfect storm
for more BwAuthority freezes.
Initially everything works fine, but 2 days later 2 of my scanners had
halted. I restarted them and another froze in about a day.
This looks similar to the problem arma raises in #3834, where the scanner
freezes without WARN, ERROR, so it may be db locking related:
{{{
INFO[Tue Sep 13 16:16:38 2011]:Waiting on consensus result: False
DEBUG[Tue Sep 13 16:16:38 2011]:Deleting ignored stream: 12028
INFO[Tue Sep 13 16:16:38 2011]:Newdesc timer is up. Assuming we have full
consensus
INFO[Tue Sep 13 16:16:38 2011]:Consensus change... Updating rank history
}}}
This problem appears to have been introduced or exposed with these
changes. The bwauth VM and my testing vm have not frozen with the old
Event Parsing code.
