New low-level optimization further lowers CPU utilization

I've further optimized some of the lowest-level process management code that is embedded in both the GUI and core engine. This new optimization will save quite a few CPU cycles, though I've not yet benchmarked it to see exactly how many it will (on average).

Of course, I don't mean to imply it really matters at this point. Once you get to as little CPU use as Process Lasso already uses, further optimizations are just bordering on obsessiveness. Still, who knows, those few CPU cycles might matter to someone, some time. Now that CPUs aren't getting much faster, instead only breeding, CPU execution speed is as important as ever.

This will be available in v4.09.05 beta. I am making v4.1 the ultimate build of Process Lasso, then letting it sit for a bit. I wasn't satisfied with v4, though users seem to have been. It was a great improvement, but I have further I wanted to go. I'm taking it 'there' with v4.1. There are several fixes and optimizations, and quite a few very important new features coming.
