No, doesn't seem to.
I tried with one and five seconds sleep.

root@powermac:/etc/udev/rules.d# udevtest /class/usb_device/usbdev1.12/
main: looking at device '/class/usb_device/usbdev1.12' from subsystem 'usb_device'
run_program: '/bin/sleep 5'
run_program: '/bin/sleep' returned with status 0
run_program: 'usb_device_name --export usbdev1.12'
run_program: '/lib/udev/usb_device_name' (stdout) 'USB_BUS\01'
run_program: '/lib/udev/usb_device_name' (stdout) 'USB_DEV\x012'
run_program: '/lib/udev/usb_device_name' returned with status 0
udev_rules_get_name: rule applied, 'usbdev1.12' becomes 'bus/usb/001/012'
udev_device_event: device '/class/usb_device/usbdev1.12' already known, remove possible symlinks
udev_node_add: creating device node '/dev/bus/usb/001/012', major = '189', minor = '11', mode = '0664', uid = '0', gid = '0'
main: run: 'deathaddercfg -C'
main: run: 'socket:/org/freedesktop/hal/udev_event'
main: run: 'socket:/org/kernel/udev/monitor'

I also tried to put deathaddercfg into PROGRAM (although that's incorrect).
Isn't called, too.

root@powermac:/etc/udev/rules.d# udevtest /class/usb_device/usbdev1.15
main: looking at device '/class/usb_device/usbdev1.15' from subsystem 'usb_device'
run_program: 'deathaddercfg -C'
run_program: '/lib/udev/deathaddercfg' (stdout) 'run_program: program '/lib/udev/deathaddercfg' not found'
run_program: '/lib/udev/deathaddercfg' returned with status 1
run_program: 'usb_device_name --export usbdev1.15'
run_program: '/lib/udev/usb_device_name' (stdout) 'USB_BUS\01'
run_program: '/lib/udev/usb_device_name' (stdout) 'USB_DEV\x015'
run_program: '/lib/udev/usb_device_name' returned with status 0
udev_rules_get_name: rule applied, 'usbdev1.15' becomes 'bus/usb/001/015'
udev_device_event: device '/class/usb_device/usbdev1.15' already known, remove possible symlinks
udev_node_add: creating device node '/dev/bus/usb/001/015', major = '189', minor = '14', mode = '0664', uid = '0', gid = '0'
main: run: 'socket:/org/freedesktop/hal/udev_event'
main: run: 'socket:/org/kernel/udev/monitor'

My deathaddercfg tool uses libusb to find the device, if that matters
(I doubt it. It seems it's not called at all).
I also tried "touch /foobar" for RUN and it doesn't create the file /foobar.
