The main problem is compatibility. If a program relies on the current

is not good publicity :)
You could make "stop" do nothing and introduce "suspend" to pause the collector. This would mean that old code wouldn't behave quite the way intended, but it would avoid the "consuming huge amounts of memory" problem.
