Hi Scott,

The operations which are registered by these non-blocking functions are put
into a queue.  Only one of these operations will be actually be executed at
a time, but as soon as one's finished the next one will start.  I believe
the queue length is 64.  If the queue is full, and another non-blocking
function is called, it will block until there's room in the queue.

Hope that helps.
