I can confirm CoCoMEM and Jr allow for more than 32 sets of task 
registers.  However, I think some utilities look at those "copies" in 
main memory.  Those apps either need to be patched, or the copies need 
to stay and be kept in sync.   If few of these utilities actually need 
the copies, it may make sense to patch.
