Subject[BENCHMARK] ctxbench 2.5.58 compared to recent and 2.4.20
The general trend of this IPC benchmark is downward. I'm going to try 
adding prempt to see what that brings. I'm having a bit of problem with
networking in 5[78], I want to resolve that first.

Two processes, passing a token back and forth uning various IPC methods.
