* Some shared memory entries and pipe entries are created
* only in one process and got shared by others. Because of
* this the real_pid member is used. It serves like a synchronization
* point -- the process which creates a particular entity does set
* real_pid member and all other users do wait until this member is set.
* real_pid member formerly served cases when
* no fork-with-pid functionality were in kernel,
* so now it is being kept here just in case if
* we need it again.
