SAPI stuff

(A reply to one of Stig's messages. Sorry, lost it due to some problems) Yes, we will need something like this for Apache 2.0. In A2 there is the concept of mpm's (multi-protocol modules) that implement the actual logic behind taking the request off of the socket and feeding it to the actual application logic. There will be a pre-fork mpm, a hybrid thread-process model mpm, a fixed-thread variable process mpm and probably a fixed-process variable thread mpm. These will all behave slightly differently and SAPI is going to have to deal intelligently with each. -Rasmus
