    Create a "libpola"?

    This also opens up the opportunity to create a pola runtime for
*nix, which would increase the range of systems on which pola-aware
apps could run. It would, of course, remain the case that pola is
less effective on non-capability OS, but at least the apps could run
elsewhere.
