I have done this, and have been running 0.1.1.26 for about a couple
weeks weeks. It appears to be leaking at about the same rate as
0.1.2.14 did.

Since this problem suddenly showed up, yet 0.1.1.26 has been out for
ages, perhaps it is a client problem? There is that issue where
clients can send too many SENDMEs and fill up server buffers.. Maybe
there is a SENDME leak?
