[Zope-dev] is threading within zope useful ?

[sathya]

greetings,

I read somewhere that each zope thread acquires the global python 
interpreter lock before processing a request and until it releases it 
the other zope threads are essentially locked out. Does that mean zope 
threads are eventually serialized and there are no benefits to be gained
from concurrent execution ? Any thoughts ?

your ideas are  much appreciated
