I belive I have found the memleak for Peters issue:

It is so small a leak it was not notices but peter's imapsync is doing a
uid ic_fetch on hundreds of ids per fetch command over and over so the
glist of ids leak would build and build on our servers but on his it
goes nuts! :)
Thanks,
Leif
p.s. Peter I am having trouble getting your test script to run on my dev
box please try the change above and let me/ the group know.

This could be a side effect of the slab allocator. Use
G_DEBUG=always_malloc valgrind ... to circumvent the glib default
allocator.
Tested with 'export G_DEBUG=always_malloc' yielding nearly identical
results (71,604,456 bytes this time). New logs at
http://rabbit.us/pool/misc/dbmail_bug584_memcheck_svn2574_always_malloc.tar.bz2
This URL has some interesting points

Erm, being a n00b and all, wouldn't this affect both imap daemons
involved in the test? In my case only 'host2' leaks, 'host1' stabilizing
at about 40M VSZ.
