Not all Unixes have light weight processes. Note that "light weight 
process" has nothing to do with whether or not it is cheap to start a 
new process on a particular OS.

That is a vast over-generalisation. All unixes most definitely do not 
have expensive threads, in fact in several of them a process is always 
layered over a thread.
