PWM OK from Console, but not in script

[diginfo]

If I run the PWM script in the console, then everything works as expected, but if I run it from a script file, then the PWM dies after a few moments:

#!/usr/bin/env python2
from RPIO import PWM
def wdog(GPIO=18,CHAN=0,FREQ=20000):
PWM.setup()
PWM.init_channel(CHAN,FREQ) ## Freq = 199,000us

if(not PWM.is_channel_initialized(CHAN)):
  PWM.clear_channel_gpio(CHAN,GPIO)
PWM.add_channel_pulse(CHAN,GPIO,0,1000)  ## 50%

wdog(22,0)

I've experienced that the PWM output seems to be reset when my scripts exits, i.e. when some object is destroyed. From other issues I've got the impression that it is due to some DMA cleanup.

What do you mean by in the console? Something like:

$ python yourscript.py

Script file? Maybe:

$ ./yourscript.py
