Awesome! That one is (while not at all necessary) VERY useful. I get so sick
of typing out:
x=x[y..length(x)]
That really gets tiring!

Very nice, esp since my new version of SySlaunch needs to be able to free
the tcp4u resources, but right now, if it crashes, it can't do that...
... and I despise memory leaks on my 64MB sdram machine...

Neat.

Couldn't get better than that, could it?

I guess it could!

Fine. Could you (at least) give an 'unofficial approximate to which you
cannot be held legally responsible' answer to what season? Winter '04?
Spring '05?

If it means it risks slowing it down, why did you rewrite part of it? It
doesn't quite make sense. What is the AdVanTage of having it be 30%
