[Dovecot] Login process connection routing

[Brandon Davidson]

Timo,

Just out of curiosity, how are incoming connections routed to login
processes when run with:
service imap-login { service_count = 0 }

I've been playing with this on our test director, and the process connection
counts look somewhat unbalanced. I'm wondering if there are any performance
issues with having a single process handle so many connections. It seems
fine (system load is actually lower than with service_count = 1), but I
thought I'd ask.
