Monitoring: db-connections

The db-connections variable reports how many database connections Archiveopteryx has open at the moment.

If db-address is a TCP socket, Archiveopteryx adjusts db-connections according to the current load. When many people are reading their mail, Archiveopteryx opens more database connections, and when people go to sleep, Archiveopteryx closes them again. The db-max-handles variable defines the maximum.

If db-address is a Unix-domain socket (looks like a file name) (and security is enabled) db-connections should be constant. It cannot grow, and it shrinks only in case of bugs.
