There /were/ unclean umounts, which probably corrupted the lists in the
first place. I'm also at a loss for why it takes so long to do
ctl_mboxlist and friends with the given options - without them, it takes
only a couple of minutes. As does the mupdate slave synchronization
thereafter (I'm using the unified config with 2.3.8, rpm).
