I agree it's useful to report the number of connections in use, as it tells the admin whether
the spawning is just to keep spares in the pool, or whether traffic has ramped up hard, and
we need a connection *now*.
In fact the *now* case should probably be a WARN, as it's likely the server is about to start
failing to process requests.
WARN("%s: %i of %i connections in use. You probably need to increase \"spare\"",
pool->log_prefix, pool->active, pool->count);
Anyway... added. See what you think.
