Re: [Texmacs-dev] Two fixes for delayed execution

[Norbert Nemec]

In fact, I found a clear measurement that indicates a problem:

Running TeXmacs/Qt on my fairly modern notebook (fully optimized compile).

I fill one page with plain text. Now simply moving through the text with 
the right arrow (no editing!) brings up the CPU load to 100%. Of this, 
95% are spent in the X server. TeXmacs itself only takes 5% of the CPU 
power.

I tried activating the code in check_event. The display is incomplete 
now, but the CPU load is down to 30% and TeXmacs feels fully reactive.

Seems like this optimization is crucial not only for slow machines after 
all...

Greetings,
Norbert
