how to keep python interpreter busy in ableton

	def pause(self):
	# helper for rconsole. This blocks ableton inside python on purpose, otherwise the console thread
	# is super slow ( python interpreter is only active when needed )

	def lock():
	if self.console_event.isSet():
	return
	# this trick works with Event and not with just time.sleep, because in python2 Event.wait is a loop+sleep, which keeps the interpreter busy
	self.console_event.wait(0.1)
	self.schedule_message(3, lock)

	it executes in less than a minute in release mode, but it ain't pretty

	main points:
	- double linked list to easily insert/split/remove
	- the nodes are not individual values, but ranges instead
	- because looking up a value in a linked list takes so long, there is a hashmap pointing to the
	slices for each value. everytime a slice is added or changed, all the values of the slice
