again instead of on the stack. This fixes the following four
	regressions but sadly it causes a 6% performance hit. It's
	probably possibly to reduce the hit a bit by being smarter about
	inlining and the way the marking list variant is implemented, but
	I'll look into that later.

	- fixed 3111500 - REGRESSION: crash in "KJS::ScopeChain::mark()" on www.posci.com
	- fixed 3111145 - REGRESSION: reproducible crash in KJS hashtable lookup at time.com
	- fixed 3110897 - REGRESSION: javascript crasher on http://bmwgallery.tripod.com/
	- fixed 3109987 - REGRESSION: Reproducible crash in KJS ObjectImp at live365.com

	Also:

	- improved DEBUG_COLLECTOR mode a bit by never giving memory back
	to the system.
