HI!
Sorry to wake up an old thread, but did you ever get this problem fixed? I have noticed the same problem that my applications use 100% cpu usage when I call the update() function from widgets periodically.

Re: PyQt4 app : high CPU usage from python and Xorg
have you run a profiler? Just because cpu is at 100% doesn't mean there is a bug with an easy fix. You should consider if you calling update will result in feedback loop of update->update->update etc.
If you have a problem, CUT and PASTE your code. Do not retype or simplify it. Give a COMPLETE and COMPILABLE example of your problem. Otherwise we are all guessing the problem from a fabrication where relevant details are often missing.
