AFAIK, KMALLOC/KFREE should be used for memory that
does not go through the gc, while gc_malloc/gc_free
should be used for the rest. Never mix the calls, or
you'll be in big trouble. KMALLOC/KFREE leave memory
management to the runtime library, while
gc_malloc/gc_free do their own memory management.

when you're dealing with java objects or data that
might end up within java objects, I think you should
use gc_malloc/gc_free. Otherwise use KMALLOC/KFREE.
Keep in mind, though, that JanosVM developers have
done a lot to improve the GC in their VM, and that has
lead them to replace most of the uses of KMALLOC/KFREE
so far with specific gc_malloc/gc_free calls. Given
that JanosVM is the place where a lot of great work on
the VM core happens, I hope we'll be able to merge in
some of the GC changes in a not too distant future.
Volunteers are welcome, as usual.
