	 *  The number of local variables should be kept to a minimum: if
	 *  the variables are spilled, they will need to be loaded from
	 *  memory anyway.
	 *
	 *  Any 'goto restart_execution;' code path in opcode dispatch must
	 *  ensure 'curr_pc' is synced back to act->curr_pc before the goto
	 *  takes place.
	 *
	 *  The interpreter must be very careful with memory pointers, as
	 *  many pointers are not guaranteed to be 'stable' and may be
	 *  reallocated and relocated on-the-fly quite easily (e.g. by a
	 *  memory allocation or a property access).
	 *
	 *  The following are assumed to have stable pointers:
	 *    - the current thread
	 *    - the current function
	 *    - the bytecode, constant table, inner function table of the
	 *      current function (as they are a part of the function allocation)
	 *
	 *  The following are assumed to have semi-stable pointers:
	 *    - the current activation entry: stable as long as callstack
