So who does the backports whenevenr something changes? You are adding
work where as the automated process would just work without this
change. It doesn't matter if there is another test that changed
the name.

If this new test has no relation to sigaltstack, then why are you changing
and renaming the sigaltstack directory? Adding a new directory is much better
than going down a path that is more confusing and adding backport overhead.

Two options:
-- Add a new directory or add a note and keep it under sigaltstack
-- Do you foresee this new growing?
