I concur.

I do recommend we dump q.empty() and q.full().  The right way is to trap the 
Empty and Full exceptions.  If needed qsize() is available to make your own 
less reliable checks.

More than just simplifying the API, the improvement makes it easier to roll 
your own Queue (like a priority queue style).  Currently, we require that six 
methods get overridden (_init, _empty, _full, _qsize, _put, and _get).  It 
would be nice to lower the burden to just the basic four.
