I have a strong suspicion that if we applied this patch it would
break running a pile of Go binaries that currently work, which means
it's something we need to be cautious about. (The Go runtime special
cases the fact that when it tries to register some signals they don't
work, but will abort on startup I think if it can't register a handler
for SIGRTMAX-1, which will be the case after this patch.)
