From b49c751749dcd3e78991463c098f8d916f52179d Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Wed, 24 Oct 2012 23:50:55 -0700 Subject: altos: Add task queues. This replaces the array-based scheduler with a queue-based one instead. It should have the same basic scheduling semantics, but it walks shorter lists for each operation, making it much more efficient when the system has a lot of tasks.
