/*
  WORequestParser (NOT FINISHED YET)
  
  A specialized parser for WO HTTP requests. It has some advanced features
  like streaming large request bodies to disk and mapping them into memory
  instead of keeping the whole thing in memory all the time.
  It also correctly works with HTTP methods that have no content-length
  specified (the NGHttpParser tries to parse till EOF by default).

  Note: since the parser keep transient state in the ivars, you need to have
  at least one parser per thread when running in a multithreaded environment.
  
  Note: if parsing fails you *need* to close the socket connection !
