For every letter I type in LyX, the updateMacros() function is called
from BufferView::processUpdateFlags().
What does this function do ? The only feature I see is that when
changing a math-macro, all uses of the macro are updated.
Is it really necessary to do this always ? As it is in a "nearly hot
path" it took 44% of the time it took to process the insertion of a
character in the User's Guide.
This function even takes longer when you have child documents as it
iterates through all child documents too.
Maybe this is one of the reasons for all the bugs on slowness:

Do I miss something critical or is it ok to start cutting some paths ?
