Almost any method for getting this data is seriously subject to race
conditions - particularly on any server busy enough for this information
to matter.

Only the running daemon has the count that is accurate (in the sense of
its the one that will be used to make connection acceptance decisions
on). Its going to be difficult to pull this out. You also need to be
aware that getting a lot of data using exiwhat is very difficult -
signal handlers are very limited.

Can't be done without making an entirely different communication between
exiwhat and exim - you are just sending a signal. I guess you could
signal everything and just filter the output. Actually you do know
which is the daemon if you write a pid file, but can we assume that?
