> Is there any chance to reap the benefit of new Generational GC merits for
> C-extension library authors?
>
> == Background
>
> First of all: RGenGC is great.  Ko1 showed that it could make significant
> performance improvement at RubyKaigi2013. (especially P82)
> ((<RubyKaigi2013-ko1.pdf|URL:
> http://www.atdot.net/~ko1/activities/RubyKaigi2013-ko1.pdf>))
>
> I guess the improvement is triggered by marking most (or all?) of built-in
> classes as WB-protected struct to work with Generational GC.
>
> == Motivation
>
> As an extension library author, I want to try to get the performance merit.
> But there is no document or guide to enable it.
>
> The PDF says "Inserting WBs step by step, and increase performance
> gradually",
> and I believe it is the greatest point of RGenGC, but there is no guide to
> proceed with the steps for now. It's sad.
>
> == Subject
>
> Could you write about it as a document, ko1 or anyone?
> I guess it's good to be written at ((%README.EXT*%)).
> (The case of ((%iseq.c%)) may be used as an example.)
>
> I'm glad to see the documents are written before Ruby 2.1 release.
>
> == Restriction
>
> Sorry for the absence of my knowledge.  Because I'm not good at
> RGenGC, I could't write the document by myself but could only request.
>
> PS
> I guess this issue depends on #3064 (sorry, in Japanse), the request of
> documenting (({RTypedData})), because there is no interface to specify
> (({FL_WB_PROTECTED})) flag with traditional (({RData})).
