Does anything use multiTHREADING with DRDOS (as opposed to multitasking,
which is easy with TASKMGR)?

I guess applications could be written with multithreading libraries to
run under any DOS - I'm not sure what is available there, but could such
programs have problems under Vladivar that are okay under Smirnoff and
Micro Softdrinks (er, MS DOS) because Vlad is being extra smart with the
CPU?

What is the current status of the DRDOS 6 memory manager - at one stage
it was suggested as an alternative for people having difficulties (e.g.
with games) under NW/Open/DRD-DOS 7.  Is it still a useful alternative
if multitasking isn't needed?

And I'd be keen to see any programming examples for multithreading.  I
do have example Turbo Pascal programs for using DRDOS multitasking, if
anybody wants them.
