Correct. void[] means the type of the data is unknown, so the GC 
has to assume it can contain pointers.

This also means that _everything_ in any void buffer has to be 
treated as a potential pointer. In other words, if you allocate a 
void buffer and fill it with ints, and one of those ints happens 
to have a value equal to the address of a GC-allocated object, 
the GC will assume the int is a pointer to that object and not 
free it.
