Andrew,

Your use of State has some style problems.

You are using a record to store the State however it contains only
one field.  Until you need more fields you might as well get rid
of the record:

init([]) ->
	{ok, queue:new()}.


However if you do plan on adding fields later keep the #state{}
record but then you'll need to update it instead of recreating it:

handle_call({in, InObj}, _From, State) ->
	QR = queue:in(InObj, State#state.theQueue),
	{reply, ok, State#state{theQueue = QR}};
