What is a “monotone” Space?
A “monotone” space (see org.mmtk.utility.heap.MonotonePageResource) will walk through their allotted address range consuming pages until their page budget is exhausted. They are typically then completely emptied (“evacuated” in GC terminology) and reset to do the same thing all over again. This is how each of the two semispaces in a semi space collector works, and how the nursery in a generational collector works.
