I'd like to avoid running another process.

In mods-enabled I can create new module/perl instance:

perl MODULENAME {
  filename = ${confdir}/newscript.pl
}

In sites-enabled I can create new virtual server:

server SERVERNAME {
  listen {
    type = acct
    ipaddr = *
    port = 1646
  }
  accounting {
    MODULENAME
  }
}

How do I specify thread pool characteristics for new perl instance?
