Yes and yes. In fact, without the multiplexor it's doubtful mimedefang
could have kept up with the load.

Same test with version 2.1 works fine. The "flooding test" is pretty
much business as usual for our mail server. I've not seen any problem
with mimedefang-multiplexor starting new perl processes prior to the
attempt to upgrade to 2.2. As I said, it looks as though a signal is
being sent back that no processes are available, although there is no
error message and many fewer than maxSlaves processes running.
