We're discussing the Lua terminal application that would fail to handle
window changes, not these others.

It has been standard practice for terminal applications; as far as
I know, nobody is writing them today in Lua.

Before making up alternatives, you need to explain what's wrong with the
existing mechanism.  SIGWINCH works just fine.  You're offering solutions
without saying what the problem is.

It seems to me that the "problem" is "Lua doesn't have a way to hook
SIGWINCH".  The obvious solution is "add a way to hook SIGWINCH", but
you're suggesting things like "introduce a whole new interface to replace
SIGWINCH", and I have no idea why.
