+ * ALooper
+ *
+ * A looper is the state tracking an event loop for a thread.
+ * Loopers do not define event structures or other such things; rather
+ * they are a lower-level facility to attach one or more discrete objects
+ * listening for an event.  An "event" here is simply data available on
+ * a file descriptor: each attached object has an associated file descriptor,
+ * and waiting for "events" means (internally) polling on all of these file
+ * descriptors until one or more of them have data available.
+ *
+ * A thread can have only one ALooper associated with it.
