Possible memory leak?

[wkbrad]

Thanks for that info.  It's definitely harder to notice the issue on small
servers like that.  But you are still seeing about a 50% increase in ram
usage there by your own tests.

The smallest server I've tested this on uses about 20M during the first
start and about 50M after a reload is completely finished.

Not so much of a problem for small servers but definitely a big problem for
large ones.  That said the issue is still there on small servers like you've
just seen.
