Split stack support already requires a stack limit in the TCB.  This could be reused even if split stacks are not used.  We'd need to add another field for the other stack end, though.

Couldn't we embedded it on pthread_t instead? I rather avoid changing TCB, since it
requires changing the ABI for some architectures (aarch64 is an example where
split-stack field is being added in a different manner).
It will be part of the ABI no matter where we put it. I don't have a strong preference in this regard. 

Thanks,
