[PHP] Multithreading for OOP PHP

[Florian Müller]

Hi guys
I was wondering, what actually the reason is that PHP itself does not support 
multi-threading?
I guess this would be realizable, or not? If not, why?
Maybe this is a stupid question, but still somehow interesting. Realization in 
a way as Java does (or just something in that way) would actually be a very 
nice thing, don't you think?
Thank you for your answers :)
Florian
