Sadly, when I learned Java for the first time many, many moons ago,
java.nio and multiplexed I/O was only a dream.

I didn't start using Java again until about two years ago, "working" on
Eclipse. (Actually, I think it worked on me!)

Yeah, it really is just that simple, isn't it? I'll put it on my TODO
list for previous heinous oversights that I've already committed.

Right now I have bigger fish to fry. When I'm frustrated with those,
this should be a mindless enough task to distract me. :-)

Thanks again for your input!
