I've tracked down (one of?) the reason(s) for applying a tag being slow --
starting at the Workflow Run Manager a call is eventually made to SQLQueryV8's
getTagClassesForExecutionLSID, and the call therein to
NamedOntClass.createNamedOntClassFromURIs(tagURI, ontologyURI) is the expensive
part, it takes about 260ms. Sean do you know if that method can easily be sped
up? An alternative might be to only (look up and) set a WorkflowRun's tags
member variable right before it's really needed, but this feels a little less
clean.
