One simple way to release clock cycles it is to make your program 
"DESQView-aware", and then loading the OS2SPEED utility (found in Hobbes). 
This utility recognizes the DV interrupt for releasing time-slices and
does the same for the DOS box. 

There is an interrupt to use for releasing time slices under DV. 
Unfortunately, I dont remember what it is, but you can get the complete
DV interrupts from a file on SIMTEL20 or ask in the desqview newsgroup.

I am using MS-KERMIT which is desqview aware in a dos box, with the
OS2SPEED utility loaded and it works great.
