Batching quota clone updates

[micah anderson]

Hi,

I like the quota count+clone configuration. However, I'm wondering if
the cloning process could batch its updates into chunks, or spread them
out over time?

The clone updates happen whenever the quota is updated, typically this
is fine, but when a tsunami of spam comes resulting in delivery to every
user on the system, then can be quite overwhelming for a sql server to
do an update for every user.

Thanks!
