Oh, I remember. I did not understand this before, but I do now. I think
the problem is that NSelect's select$from$into is not declared in Swarm
as a static method. If I try to use it, the compiler says:
Recruiter.java:516: non-static method
select$from$into(int,java.lang.Object,java.lang.Object) cannot be
referenced from a static context
NSelect.select$from$into( number, listplaceholder1,
listplaceholder2);

Can do later if my previous surmise is wrong.

Yes. I just tried that, even before you said it! Using Colt's static
Uniform object in NSelectPJ reduced the runtime from 7min50sec to
2min30sec, a pretty big improvement. I'm getting down into the 1/2 as
fast as Objective-C range, so some of the little optimizing steps will
start to make a difference. I hope.
