One must realize that these are just hacks to get around their
phenominally slow operating system. If they had done the task
switching right in the first place, it wouldn't be an issue.
I can make a fibre under FreeBSD too, it's simple:
switch(from,to)
pushal
movl %esp,FIB_SPSAVE(from)
movl FIB_FPSAVE(to),%esp
popal
ret
Not a big deal...
