It does, to some extent.  First, you have less memory in the child 
program.  Second, the hardware keyboard handler installed by every DJGPP 
program steals a few cycles from the child (assuming the child chains to 
the previous keyboard handler).  Whether these issues are of any 
significance in your case is something for you to test and decide.

The memory-related issues are further discussed in section 15.8 of the 
DJGPP FAQ list.
