	Test a Stomp 1.1+ duplicate header shovel.
	The Stomp 1.0 specification level is silent on the subject of duplicate
	headers.  For STOMP 1.1+ this client package is strictly compliant: if user
	logic passes duplicates, they are sent to the broker.
	The STOMP 1.1 and 1.2 specifications:
	a) differ slightly in specified broker behavior
	b) allow quite a bit of variance in broker behavoir.
	As usual: YMMV.
