To be honest, most of that was gibrish to me (NTPL, futex, sysV..).. Most of 
my experience with system calls is with pipes and files, I know very little 
about these other things...
Either way, you are a bit late, just half an hour ago, I have completed my 
program, and it works. :) I finished the pthread instead of select() 
implementation pretty quickly (now I understand why lazy programmers use 
threads.. heh), what took me so long was troubles with the 2 other programs, 
had to refine their command line params carefully...
(btw, the 2 other programs - MPlayer and MEncoder, and my job was transferring 
video AND audio between them.)
