Given its function to "killall5", how can sendsigs discriminate
between processes to be killed and those to be preserved?
How can it know which daemons were started by a named service
(udev in this case) so it can skip sending SIGTERM to them?

I think what sendsigs has provided for this purpose is the
/run/sendsigs.omit.d/ directory, as documented in
/usr/share/doc/initscripts/README.Debian.

And to add a process to the omission list, a most appropriate
place to do so is udev's init script itself, where the daemon was
started. That's why I reassign the bug to it.
