[Dovecot] Effect of "login_process_per_connection = no"?

[Pete Slagle]

Using dovecot version v1.0.beta8 on FreeBSD 6.1_RELEASE with

    login_process_per_connection = no

in the dovecot.conf file, I still get a new imap process for each IMAP
login.  That is, if a single user logs in five times, five imap
processes are created.

The difference appears to be that with a "yes" setting each user login
causes a new copy of the imap-login processes to be forked, which then
creates the imap process for the connection and exits. With a "no"
setting, one of the existing imap-login processes creates the imap
process directly (and does not exit).

I am understanding the effect of this control setting correctly? Are
there other actions or implications?
