This is a perennial topic in this list.  Without meaning to dwell too
long on old arguments, I simply ask you to consider the following:

- Do you really think a concurrent GC with shared memory will scale neatly
  to those 32 cores?

- Will memory access remain homogeneous for all cores as soon as we get into
  the dozens of cores?

- Have you considered that many Ocaml users prefer a GC that offers maximum
  single core performance, because their application is parallelised via
  multiple processes communicating via message passing?  In this context,
  your "bug" is actually a "feature".

Best regards,
Dario Teixeira
