     I actually never sat down to use timeslices except for a few
     Java programs.  The only close to that would be simple
     program/execution delays.  With that said my experience with
     such is just not as high say as some.

     The problem is that with today's modern compilers and computers
     getting faster and faster every day timeslices get less
     and less value.  A timeslice for a old 286 is just nothing
     for a 5 gigmhz machine.  So you have to adapt your timeslices
     for the actual cpu speed.  So if you really really want
     to get involved you should get code to detect the cpu speed
     and then modify the timeslice accordingly.

     Another thing is why do you need the timeslice?  A multi-tasking
     software? A TSR? A game?  The particular type of software
     also indicates how to go.  A game sometimes need fast and
     sometimes slow timeslices, for example.

     Now with that stuff said have you checked out SWAG?  It has
     at least 3 sample codes using the keyword time slice in it.
     One for os/2 and Desqview and 2 others general code sources.
     Keep in mind though those are in pure assembler.  But ASM
     is a good way to go with timeslices.
