what does filesystem have to do with ext-todo?  ext-todo is for high
injection rates, where qmail-send will spend more time pre-processing
messages than delivering them.

Now, I admit that there is some missing information before we can
properly diagnose silly qmail syndrome... we haven't seen his qmail-send
logs, so we aren't sure if he's maxing out his remote concurrency (if he
is, he's not suffering, if he isn't, he is suffering), but ext-todo
still doesn't have anything to do with filesystem.

Unless, of course, he's using a network filesystem, like nfs, for the
queue.. which itself would be just stupid :)
