If you don't have a lot of cores, then running the GC in a purely concurrent way can be bad: you won't make enough progress to keep pace with the mutator's allocations.

Fortunately, Riptide has most of what we need to run increments of GC work on the mutator thread. This is the most natural way to pace the mutator, since it forces the mutator to do GC work anytime it allocates.
