 I also have the same problems with fork I only need native unix/linux
fork like done the last 20 years.
 I figured out that the fork system call does not work with threads I
dont know why so long I found
 no reason what happens. If I do not start the thread the same code
works well. Using the system call
 I have no problem to start a second task but then I dont have the
 process id to send a signal when the
 first process exits. I also do not need pipes and stuff like this I
communicate with shared memory.
 By this way setting up named pipes for sync communications is really
easy and do not need calls I dont know
 what happens behind
