Not me.  But BTW: I once wrote a patch that enables master to behave like
the subprocesses when given a "-C" at command line.  See imapd(8) for de-
tails.  I tried several times to get it into some mainstream release, to 
no avail  :-]

Maybe the patch still applies (AFAIK my last working test was with 2.1.2),
its quite small and might be changed easily to fit with 2.1.4.  In case you
use 2.0.16, it applies very neatly.
