Description:
------------
Process "A" has a number of open network stream sockets and watches those sockets via stream_select. Some are in "accepted" state (the connection has been established). Process "A" maintains static connections (think IRC) itself while http-connections are passed to pcntl_fork() after being accepted.

Let's say parent process "A" has accepted #23 and #24 . #24 is handled in a daughter process "B". If "B" exits .. or fclose(#23) is called by "B" , the resource #23 in "A" is also terminated. According to the (C-) norm. file descriptors should be copied and closing them in a fork()ed process should not influence the master process. Same should be valid for stream resources.
