Use pcntl_fork() to create a child process (or, if posible, a thread) for
each site request. As all the children share the same stdout file
descriptor, you should be able to echo() text to the browser asyncronously
(or, you could use popen() or some other pipe mechanism to centrlize the
output).
However, this approach has the disadvantage of potentially becoming a
concurrency hell. Make sure you have the proper inter-locking mechanisms to
access the shared resources (in this case, stdout).
