The reason I didn't suggest UMA is that UMA already has functions that
do the cleaning when destroying an object... You can't just zero UMA
objects on free w/o calling fini, otherwise you might leak resources..
Plus, it would be a lot of work to fix all the UMA consumers to make
sure that their uminit/fini fuctions do the proper cleaning necessary...
