That sounds great.

As new contributors please review the "Contribution Checklist":

Bug 22850 is a difficult bug that covers multiple subsystems and will
touch all architectures. It requires considerable skill to get all the
details right.

So far there is no attempted implementation in glibc where the TCB
and associated data is split from the thread stack.

A related bug is:
"Program with large TLS segments fail."

Removing the struct pthread, the TCB, and TLS data from the stack
would make the stack extent computation much easier.

Someone needs to design a solution and present it to the community
with their evalution of the pros/cons of such a design.
