piui_demo.py works just for a while. #10
Description
Hello, I installed piui the do-it-yourself way. I configured the init.py file so it now uses directly port 80, buty I have to start the demo with sudo because normal users don't have permission to use port 80.
I did that to access piui just putting the Rasp IP on the browser.
The thing is, after I start the demo script, I am able to access the piui interface, but after pushing some buttons, it starts to get sticky, until it is completely unusable and I have to kill the executing code and run it again to be able to access.
I guess this is the normal whay piui do things:
When I start to run the script, it displays this on the terminal:
pi@raspberrypi:/home/piui $ sudo python piui_demo.py [17/Jul/2016:21:40:04] ENGINE Listening for SIGHUP. [17/Jul/2016:21:40:04] ENGINE Listening for SIGTERM. [17/Jul/2016:21:40:04] ENGINE Listening for SIGUSR1. [17/Jul/2016:21:40:04] ENGINE Bus STARTING [17/Jul/2016:21:40:04] ENGINE Started monitor thread 'Autoreloader'.

It stays that way until I access piui, when I open piui, it starts to output this:

After that, if I navigate on the site, it eventually starts to get stuck.
- Sometimes, it takes some seconds to respond.
- The "Back" button stops working.
- Pages are loaded partially or take too long to respond.
I guess it is the same ploblem other dude reported.
I am using Raspbian Jessie on a Raspberry Pi 2.
I noticed that sometimes, when it gets unstuck, it outputs something different on the terminal:
