They're both pretty inefficient.  Adding a root or range is pretty
fast, it might have to resize its internal array.  But removing a root
or range requires the linear traversal of the internal list of roots
or ranges as well as copying every root/range after it down a slot,
which is all very slow, as downs has found out (and patched, though
it's not in the official GC yet).
