Well, if you do that, then max_connections is really not max
connections, it is maximum connections minus admin_connections. That
seems confusing.

I think I prefer just reserving 1-2 of the last slots. The kernel's
proc code is the same; if you specify a proc table of 150, it is 150,
with 149 and 150 reserved for root.
