Yuck; that's a bit too ugly for generic code.  Will there be other places
that this needs to be used?  If so, we'd probably need to encourage its
use where appropriate, which is even uglier but we cannot avoid it...

Also when the underlying system does not know the executable bit, how
would this help?  I thought that earlier you said the part that checks if
it wants to execute hooks with access(X_OK) will fail, so...
