From man udev's section on RUN:

"           This can only be used for very short-running foreground
tasks. Running an event process for a long period of time may block all
further events for this or a dependent device.

           Starting daemons or other long-running processes is not
appropriate for udev; the forked processes, detached or not, will be
unconditionally killed after the event handling has finished."

Instead of using RUN, use SYSTEMD_WANTS to start a .mount or .service
unit that does your job. In the remove case, use
RUN+="/usr/bin/systemctl stop --no-block foo.mount" or similar.

(Not that I think this is a good idea at all: Your volume will be
"unmounted" after it has been remove already - you are asking for data
corruption.)
