	Multiple threads in the same program are not impossible in Djgpp, there
are some packages that accomplish this like LWP or PDMLWP with several
degrees of reliability. But, if you are talking about games you don't
need multithreading, it is possible to achieve this kind of
functionality by writing a proper data structure and algorithm.
	Remember (if you are old enough) that most video games (mainly the old
ones) didn't have anything similar to threads.
