Log message:
	Eliminate references to RTHeapDep.VM/RTCollectorSRC.incremental since we are
	now using read/write barriers inserted by the compiler.  This means that the
	hack to change the cursor to "StarTrek" is no longer meaningful for incremental
	GC, since the GC cycle is interleaved with mutator execution.  To turn on the
	cursor use the @M3StarTrek runtime argument.  Your mileage will vary!
