The rootTable is used during incremental GC. Its contents are those objects in old space that are roots for objects in new space (see ObjectMemory>>beRootIfOld:). It has nothing to do with the (global) roots of the interpreter; in fact the root table is cleared right at the beginning of fullGC (see senders of #clearRootsTable). The global roots are explicitly enumerated in Interpreter>>markAndTraceInterpreterOops.
Not sure whether it is worthwhile to change such details, but I belief the standard terminology would be 'remembered set'. At least that is the typical name for recorded references between different object sets maintained separately, AFAIK.
And it could avoid confusion.
