[movitz-cvs] CVS update: movitz/losp/muerte/los-closette.lisp

[Frode Vatvedt Fjeld]

Update of /project/movitz/cvsroot/movitz/losp/muerte
In directory common-lisp.net:/tmp/cvs-serv26048

Modified Files:
	los-closette.lisp 
Log Message:
This rather substantial check-in is a clean-up of all things related
to dynamic memory allocation. In particular, the separation between
the muerte kernel with its 'default' memory management (which simply
allocates objects consecutively until it runs out) and the los0 GC
implementation is improved.
