Oops, I did not see the '&' in the system() call. That means that the 
process is launched in background while the parent process dies, hence 
only one PHP stays in memory.

However depending on your setup you may run into problems: the child 
process may get a SIGHUP for instance, once its parent dies (depending 
how the initial process was launched)

Regards,
