Thanks; I've now applied this to Emacs 28.

The remaining operating systems that uses the broken_SIGIO code paths
are pretty obscure -- I guess Solaris is still used to some degree.
Hm, let's see... I guess the code paths that are exercised are the ones
where USABLE_SIGIO is undefined? Do you have a simple test case for
this (on Ubuntu, for instance)? I think it might make sense to open a
new bug report for this.
