I never thought the hard internals of the Ruby heap would interest me. Your article got me hooked after the first few paragraphs. A great read. Your effort was not in vain.

Imagine a C function which allocates a RString str1 and then a RString str2, but there is not enough space to allocate str2 so the garbage collector runs. At this point, since the only reference to str1 is in the system stack, the garbage collector would mistakenly free str1 if it didn't scan the system stack.
