Not sure where you're going with that, but the specific issue I had in
mind was SA child processes waiting on the results of a DNS query (e.g.:
RBL lookup, etc.).

And in the context of the current AOL issue:  RBL lookups are one of
several factors that SA looks at, with the weighting being based on
actual corpuses of spam and ham, and on the actual predictive value of a
given observable characteristic.
