Good!

It is a debugging metric we added to see if our event multiplexing
infrastructure is operating as well as it could. Can you give me the output
of 'rec_control get-all' after some time of operation?

It is probably of no concern, but it might waste some CPU cycles. Probably
no-packet-error is a lot smaller than your number of questions and
outqueries.

great!
