Removed the push for ECX and EDX ( the others are used internally ). It
seems to work. Many thanks! :)

Still runs somewhat slower than Fibers, though. I can't imagine why.
Also, oddly, GDC doesn't allow me to push EBP in -O mode and D inline
assembly. Works in native GCC assembly. *Very* odd.

Aww. Still thanks for answering. I'm sure somebody will know it.

Braaaaaaaaaaaaaaains!


Actually, it started out with a piece of code that looked like this

Clearly, the addTask is redundant here.
I replaced it with

Somebody in IRC pointed out that the stuple was redundant.
He must feel horrible for indirectly causing this.

Then I noticed the info calls were also redundant. It went kinda out of
control after that. You know the result. :)
