For me at least, raising an exception in a callback does not do anything to the request

	from tornado import ioloop, web, httpserver, httpclient

	PORT = 8080

	class TestHandler(web.RequestHandler):

	@web.asynchronous

	You give it a (partial) map and it plots a route using naive BFS.
	As you discover more obstacles you can call addWater() for them.
	It makes extensive use of pre-allocated data for intermediate results,
	so you must extract the path for each call to findNearestAnt() or you
	lose it. */
