The best thing you can do for you self is get on the phone and call
South Mountain Software (201) 762-6965 and order a copy of HOLD
EVERYTHING and Resident C. These guys did all the home work for you
and it even comes with source code. I have released 4 commercial
products with these tools and they work like a champ. They do not
break mysteriously and yes, you can spawn children in a context
sense with them.

TSR's can not directly spawn a child process without first
suspending the forground task and swapping it due to the
non-reentrant nature of MS-DOS code. BUt, you can background task
in a time slice and do lots of different things, such as background
communications, disk I/O, printing, etc.

I know they work with C6.0, since one of the products I wrote was
done that way.

Good Luck...
