background and forground process interaction

Hi,
I have noticed that there several times while I am editing the
background process to do the parse(s) for the suggestions module kicks
in, when my cpu was already busy doing something else, e.g. code
completion, and the UI lags because of this
 
I have a few ideas. I am not sure that these are issues for this
tasklist, or general NB issues
 
1. when an action is an intensive application, such as the code parse
for the suggestion module, pmd etc, and the action is kicked of
automatically then could the priority be lowered
 
2. could the varios suggestion providers affect the scheduling of each
other, e.g an option so that only run PMD iff there are no compiler
errors.
 
3. could the suggestion providers detect user activity and stop their
current run (sometimes I get several code warnings about the same word
that I am typing, each with one morecharacter typed than the last! When
the happens the UI is really slow. As a non touch typist I dont usually
get 2 words ahead of the UI! (yes I do have a slow machine...)
