Not sure.  AFAIU, gmalloc-mmap-ralloc suffers from fragmentation, which
was the reason why ralloc was written in the first place, so I would
tend to shy away from it, but I have not personally seen those problems,
so I don't have a strong opinion on this.

As for using HYBRID_MALLOC, that would be a better solution I think, but
I haven't looked at the corresponding patch, so I don't know how safe it is.
