AFAIK, CS launches one process for every connection, while SS handles every
connection in only one process. Since FB communicates through TCP, and uses
INETD, the maximum number of connections limited (or unlimited, if set). As
I can remember, earlier on this list there was a discussion about this
issue, and about where to edit this number.
