No I am not sure the interrupt vector will work under SMP.  It looks like
your code is much better.

I actually ported to MSVC, but I had to stub out all of cygwin.  The 3 major
reasons
I dont really work on line is that
1) I get really frustrated using GDB/emacs under cygwin.
2) I really dont know enough about linux

>Do we realy need full Cygwin implementation???
My gut feeling is that Line and cygwin are entirely different beasts. Line
implements
the linux API while cygwin implements the c runtime. If I were paid to
rewrite
line,  I'd
1) make interrupt 80 reflect through an LPC port to a ring 3 process
2) implement the linux APIs in the ring3 process
3) move that implementation to the ring 0 interrupt handler.

The result would be much..much different from line and a HUGE project.
