hi,

setup following :
1. raspberry pi, in case version 2, have used b , b+
2. dht22/am2302 connected approx 10cm long wires, connected gpio4
3. code http://www.pridopia.co.uk/pi-user-manual/a4-dht22.pdf (python command line variation)

code has been working in previous installations quite ok, hangs. see dht-process running in top consuming quite bit time. have tried several sensors , tried several gpio's. no luck. also, out of curiosity tried code access non-connected gpio, exits properly.
