Unfortunately, my test code is proprietary, as it relies on
some deep (and hard won) knowledge of the BSD stack.

It's pretty trivial to build code that can run on 25
client machines tuned to 10,000 fd's each, and a server
that just forks and accepts connections will leave you
some idea of how much remaining capability there is on
your target server, after tuning, to do actual work.
