 Not quite so. The user is not all of 'else' that may be happening. If Strigi 
starts indexing after 20 seconds of user inactivity, then it may kick in e.g. 
after I start compilation and sit back to watch the output, thus actually 
starting at rather bad moments (since otherwise it might index while I'm 
typing the code, which causes much lighter CPU/IO load).

 If you really want to index mainly when nothing else is happening, you need 
to watch the system load. The user inactivity timeout may still be a nice 
addition, but I would suggest a noticeably higher timeout that would mostly 
mean that the user really is not doing anything at the moment.
