Actually ... this is EXACT quota using a dynamic window ... the only way
to make it more exact is much much bigger floating point numbers :D

Fixed window quotas is imho alot less accurate ..... 10:55 => 11:00 ,
allow 10 mails .... that means you can send 10 mails at 10:59 and 10
again at 11:00. Thats 20 in a 2 minute period.

2.0.11RC1 + Robert Anderson's patch should have no bugs and is
extensively tested. If you having any problem with 2.0.10 I'd strongly
suggest trying 2.0.11RC1 + patch. If you have any problems with that
we'll investigate and fix in a priority fashion.

I'm going to be releasing RC2 in the very near future, hearing people
say "works, awesome" motivates :)
