Hi.

We are thinking of changing GO32 to support multitasking (preemptive).

The basic idea is to change GO32 code so that it will allow running several
programs (compiled with DJGPP) simultaneously.

For that, we'll create or adapt a shell (like C-Shell or Korn shell...)
in which the user will be able to launch programs interactively...

Please note that we are not interested in running normal DOS programs
inside the shell, only DJGPP-compiled programs.

MAIN TOPICS:

* How does VPCI match with multitasking?

* Where should we implement the multitasking kernel:
  above VPCI or under?

* Is the 387 emulator reentrant? Will we have problems there?

* The BIOS calls are not reentrant. If we use VPCI will it solve this 
  problem? And about DOS?

In short, the idea is to have a 32 bit DOS extender with preemptive
multitasking, providing the programmers with the fork() system call and
related functions and so on...

Please tell us about your ideas about this project.
