GC-related

Hi,

BTW, is there a Rubinius related mailing list? I couldn’t find one!

If not, here is my problem/question:

I’ve a lot of C++ objects, and wrap them in Ruby objects (just like
every C/C++ extension does using Data_Wrap_Struct). This creates the
same amount of Ruby objects of course. I’d love to avoid this overhead
by allocating a few more bytes for the C++ object to then “embed” the
Ruby object into the C++ object (or vice versa). But that doesn’t work
with MRI/Ruby, because the GC assumes the allocated memory to be within
a well known memory frame and of a special size or aligned, mainly due
to reducing overhead when doing a conservative cycle (or that’s how I
understand it).

How is it done in Rubinius? Is it possible to allocate any number of
bytes per Ruby object? In-line?

Thanks in advance, and Merry Christmas!

Regards,

Michael
