--- Comment #4 from Wei-Cheng Pan ---
I commented out this line:
m_parser->updateProgressBar();
in
KDevelop::BackgroundParserPrivate::parseDocumentsInternal
and the GUI thread becomes idle and works normally.
Maybe we can decrease the update frequency

This report was measured after I commented out the line I mentioned before.
Looks like there is another fun

It's KDevelop::BackgroundParser::parseComplete emitting the signal.
We'll need to add a timer to update the progress bar, instead of notify the
main thread in every single step.
