I sent the following note to erlang-bugs two days ago and have not seen
anyone comment.

This is not the first email about runtime internals that I have sent
which has gone without comment, and so I am wondering if the people with
detailed knowledge of the runtime do not follow these lists.

Is there a better place/way to get in contact?  (What I am really
looking for is a discussion of the overall internals design of the smp
runtime structures, so that I can get a jump start on fixing these types
of thing myself.)

thanks in advance,
