As I understand it, it's an API to allow multitasking within a process. 
This can be helpful for identifying which parts of a program can run
independently, and also can allow multiprocessor machines to be used
effectively.  I haven't used pthreads, though I have looked at some
documentation.  I believe that one begins by `creating' a thread which
runs a particular function, and `joining' it again later, when it cannot
run asynchronously any longer.  There are other complications with
signals, locks, etc, etc.

IMHO, pthreads is unlikely to be productive for a DJGPP-only app (there
is no multiprocessing support in any version of DOS that I know of),
though the DJGPP implementation could be helpful for porting apps which
use it.
