note 48377 deleted from function.pcntl-fork by nlopess

Note Submitter: Jon Dowland <bugs at alcopop dot org> ---- I thought I should add a quick note to clarify the mentioning of threads below. This procedure does not create a new thread: a thread is a seperate execution strand within the same process. So, a thread has access to the same memory as the parent and no duplication of process space is done. A fork is a relatively expensive procedure as the parent processes memory segments are copied. I don't know the internal PHP implementation details but this most likely includes the PHP interpreter. A child does not have access to the memory of the parent: only a copy of it.
