Looking at POSIX e.g., is there anything in the spec that makes this

boosting, I do not see what could break in principle.

It is nothing I would design into some app, but we should somehow handle
it (doc update or code adjustments).

Except for its dependency on XNOTHER which is not updated on RT->NORMAL
