 Description 
 =========== 

 States 
 ------ 

 The FastCGI state machine currently consists of six states, 
 each of which is visited in turn as a connection is processed. 

 :init: 
   prepare for a connection 
 :connect: 
   wait for a connection 
 :prepwrite: 
   build the request 
 :write: 
   write the request to the network 
 :read: 
   read the response from network and push it to the write queue 
 :close: 
   terminate the connection 
  
 Delays 
 ------ 

 The connect, write, and read states may need to wait for an fdevent. 
 The delays are represented by loops in the state diagram below.
