Thread support in Nginx

[cachenewbie]

I was thinking that the in-memory buffer cache can be shared by multiple
threads (can't be done by multiple processes without shared memory and
shared memory isn't good for performance) serving different
clients/requests instead of multiple processes sharing the file cache -
basically to help having two levels of cache - one in-memory and one
file-cache served by multi-threaded multi-process nginx system making
the best use multi-core processors.
