Not exactly.  It's a very simple 3 color incremental mark-and-sweep
collector (which is not generational or moving) using hardware write
barriers to keep track of changes made by the mutator.  I tried to keep
the design of the existing garbage collector intact as much as possible.

The motive was to get rid of the noticeable freeze during garbage
collection instead of making GC itself fast.

Which algorithm(s) were you considering?  I think that information might
be useful.
