Python pigpio use 100% of CPU if pigpiod daemon stops

[cescobaz]

Hello everyone! I noticed that when a python client is connected to the daemon (via TCP socket) and the daemon stops then the client go to 100% of CPU.

How to reproduce:

1. start the daemon on your raspberry

sudo systemctl start pigpiod

2. run the following python program on your PC

# proof.py
import time
import pigpio

pi = pigpio.pi("192.168.1.104") # use your raspberry address

pi.set_mode(17, pigpio.OUTPUT)
pi.write(17, 0)

time.sleep(50000)

python proof.py --debug

3. stop the daemon in your raspberry

sudo systemctl stop pigpiod

4. look at the python process on your PC should be a 100% of CPU and there it remains

If you do pi.stop() the CPU come back to normal, but how can I prevent this behavior?
