Add throttle mechanism?

[casperlamboo]

To prevent crashing of the small webserver on the WiFi-Box it might be interesting to look into a throttle mechanism for all rest calls. This could queue requests that come in to quickly after a prev request. Finding a way to give priority to some calls would also be important, to prioritize print calls for example.
