I debugged it a little and come up with a 2 lines patch that fix this memory
leak. The idea is to always finish the sweep before the compacting; Otherwise
you may be compacting a heap full of garbage. Worse, in my case I am
producing garbage faster than the incremental sweeping can get to them so my
heap just keep growing. Please apply.
