Thanks Rikki,

I saw that before, but I was left with the impression that its 
doing blocking calls in a thread (which could very well be the 
simplest answer). I'll give it a bash.

I wrote an equivalent program in C# using the asynch socket calls 
and the Task Parallel Library and the result was at least a ten 
fold speed increase. I would like to match, and preferably 
better, that performance in a D program. I realize that the task 
is predominantly network bound so D doesn't get much of its 
native advantage.
