I just posted (to Niklas) what will likely be the solution- a large array indexed by socket number. That is prolly the cleanest way I can do this cheap, at the expense of a little bit of memory.

Agreed. In my day job (where we try lots of things), I do benchmarks on the C++ servers I write and maintain.  Experience shows that it takes very little to slow down the transaction rate and there are often surprises.  

Here though, in Ada, I'm just playing around with a version of it as a hobby horse. It would be nice if I could someday compare the Ada version against the C++ version. So I'm just chipping away at this.
