The cuckoo code may enqueue a million events onto a queue.

When queues are implemented as bounded buffers, a default
queue size can be used during queue create, otherwise this
information needs to be passed down from the application.

The reverse information flow, default queue size passed up
to the application via capabilities, currently has no known
use case.
