If you read that and understand what they are doing, then you can change the logic and create a script that will count the number of connections and if there are 5, deny any more connections. You will probably want to insure you also kill off any terminal processes that are idle for more than xx amount of minutes to insure new connections can come in and aren't waiting for folks that are just idle and doing nothing (info on that page will explain how).

dbd::gofer::transport::null
DBD::Gofer::Transport::null(3) User Contributed Perl Documentation DBD::Gofer::Transport::null(3)
NAME
DBD::Gofer::Transport::null - DBD::Gofer client transport for testing
SYNOPSIS
my $original_dsn = "..."
DBI->connect("dbi:Gofer:transport=null;dsn=$original_dsn",...)
or, enable by setting the DBI_AUTOPROXY environment variable:
export DBI_AUTOPROXY="dbi:Gofer:transport=null"
DESCRIPTION
Connect via DBD::Gofer but execute the requests within the same process.
This is a quick and simple way to test applications for compatibility with the (few) restrictions that DBD::Gofer imposes.
It also provides a simple, portable way for the DBI test suite to be used to test DBD::Gofer on all platforms with no setup.
Also, by measuring the difference in performance between normal connections and connections via "dbi:Gofer:transport=null" the basic cost
of using DBD::Gofer can be measured. Furthermore, the additional cost of more advanced transports can be isolated by comparing their
performance with the null transport.
The "t/85gofer.t" script in the DBI distribution includes a comparative benchmark.
