A Contiki process is made up of a protothread, which is a more low-level 
concept than a Contiki process. Contiki processes are scheduled by the 
Contiki kernel (they can receive events, can be polled, can be called 
from other processes). A protothread by itself cannot receive any 
events, and must be scheduled "manually" by the process that runs it.
