However, they are executed on arbitrary threads within GCD so __special attention must be paid to thread-safety and re-entrancy__.
 
 Handlers require 2 GCD blocks:
 * The ```GCDWebServerMatchBlock``` is called on every handler added to the ```GCDWebServer``` instance whenever a web request has started (i.e. HTTP headers have been received). It is passed the basic info for the web request (HTTP method, URL, headers...) and must decide if it wants to handle it or not. If yes, it must return a new ```GCDWebServerRequest``` instance (see above) created with this info. Otherwise, it simply returns nil.
