Pthread are more efficient than Fthread as each Fthread is backed up with
exactly one Pthread. 

Generally speaking, I'm not sure it would a good idea to start a fresh thread
for each HTTP connection established on the server. Using a thread pool
is probably a good idea.

No. You can use non blocking IOs with fthreads but, once again,
blocking/non-block IOs is not a critical problem is you use pthreads.

I repeat my advice, have a look at Hop. Even if at the end of day you
prefer not to use it, I'm pretty certain that you will find answers to
many of your questions about the efficient implementation of a Web
server.
