Finalizers and incremental GC

[Po Lu]

In my incremental garbage collector, finalizers are currently run every
time a finalizer is swept.  This means every time Emacs enters garbage
collection during the sweeping phase, only a small amount of finalizers
are run.

Would it make more sense to run all the finalizers at once, after all
white objects are swept and a garbage collection cycle completes, like
the current garbage collector?

I can't seem to find any code in the wild actually using finalizers.
