It's not a lot, but the computer is basically idle, and qtile is using the
most of CPU.
I found a way to profile qtile with the help of qsh here
<https://github.com/qtile/qtile/issues/754>:
eval("self.pr = __import__('cProfile').Profile(); self.pr.enable()")
eval("self.pr.disable(); self.pr.dump_stats('/tmp/qtile_profile')")
I sorted the statistics and printed the top 10 functions:
/tmp/qtile_profile% sort time
/tmp/qtile_profile% stats 10

Any ideas?
