The thread doesn't seem to be wrapping up, instead it appears to go in
circles :-)

As a glibc maintainer, when it comes to this issue, I am guided by:

(1) This is a distribution problem and the solution needs to come from
a consensus among the distributions.

(2) The gcc/glibc community should listen to the distributions.

The distributions have the most experience when it comes to
whole-system issues. I certainly don't have that experience.
Unfortunately *I* give the distributions a B- or C+ for communication.
Please make it easy for me to give you an A. It is exceedingly
difficult for me to review solutions that span multiple patches,
emails, mailing lists, and communities. The best way to avoid
rehashing old problems is to document the design and get sign off from
the interested parties.

If I see uncoordinated and conflicting responses from the
distributions... I get worried.

Is there a proposal on a wiki that begins to summarize the suggestions
and solution?

Cheers,
Carlos.
