Nothing seemed to help, until I tackled the only real difference in the
imapd.conf files, namely:

<   imap                cmd="imapd -C /etc/imapd.conf.m2_2.master" listen="" prefork=5 provide_uuid=1
<   imaps               cmd="imapd -C /etc/imapd.conf.m2_2.master -s" listen="" prefork=5 provide_uuid=1
<   pop3                cmd="pop3d -C /etc/imapd.conf.m2_2.master" listen="" prefork=3 provide_uuid=1
<   pop3s               cmd="pop3d -C /etc/imapd.conf.m2_2.master -s" listen="" prefork=1 provide_uuid=1

..the prefork numbers. Now this is something. I don't really know which one of
these is the one that matters, what is the resource that gets exhausted, why it
gets exhausted etc. (and I sure as <expletive deleted> hope the problem only
manifests with a large prefork number, not when my system is in production and
has many more than 25 simultaneous imapds... well, it's easy to test...)
