Is there any plan to fix thread support in Nginx ? Are there significant  
drawbacks in running multiple threads in each Nginx process ?

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.
