The multitasking/multithreading exists on Novell DOS since about 1994.
Now it is Caldera DR-DOS 7.02.
Until recently, the built-in DPMI server did not function in a 32-bit
context; DJGPP tasks used CWSDPMI and were inactive as background tasks.
But this has changed ! Their new EMM386 3.25 at least allows simultaneous
DOS tasks with DJGPP (or GNAT/DOS) programs running. If a multitasking
crack could try to make threads etc. run with DJGPP it could be _wonderful_ !

The full doc about threads, syncronization etc. is there:
http://www.caldera.com/doc/dos/progdoc/multtask/index.htm

The new EMM386 3.25 is there:

NB: you can download DR-DOS for personal/evaluation use - via http or
anonymous ftp !
