Paul et al.,
The next steps for this issue are:
(a) Rewrite the patch to adjust the default stack size in nptl/nptl-init.c to
account for large TLS data as *additional* space.
(b) Find people from each of the major distributions to comment on this issue.
Asking them the pointed question "Would you mind if the memory footprint of all
applications that use TLS goes up by the size of the static TLS in order to
provide assurances that your application will have some reasonable amount of
thread stack not consumed by the TLS data?" I suggest: Jeff Law (Red Hat),
Aurelien Jarno (Debian), Andreas Jaeger (SuSE), Ubuntu (??), Mike Frysinger
I'm here to guide you, but this kind of work needs to come from the ground up
and from the people most interested in seeing this fixed. We need volunteers
like you on the product to help fix these kinds of issues, but it does require
some work to reach consensus :-)
