I think you may have fallen for Microsoft FUD.

In the Early Days of Windows Microsoft was appalling Bad at 
multiple processes....

Rather than fix their OS, they cranked up their Marketing machine 
and Hyped threads as "Light Weight Processes".

Unixy land has had "COW" (Copy on Write) page handling for years

being "light weight processes" is definitely not one of them
