Unfortunately, it's not such simple. signal-process can also deliver a
signal to a process running on a remote host. The signal names on that
host might differ from the signal names on the local host, collected by
Fsignal_names.

How do we want to handle this? I don't see a simple solution, because
the file name handler machinery is not in use here.

Best regards, Michael.
