Subject: [Rubinius-question] 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
