I don't think this test is relevant  - just the fact that the IDE is running 
on
the background and consuming resources is slowing down the build. In my 
opinion
the more relevant test is to run IDE on background in both cases - just in one
case to include the switch to turn off the listening to filesystem changes.

I've made some measurements, the setup is: two systems - relatively fast 
ubuntu
and old slow XP. On both of them three scenarios were measured : 
1. build all clusters with nothing else running. 
2. build all clusters with netbeans with filesystem listening turned off
running on background 
3. build all clusters with regular netbeans running on background.
In both 2. and 3. java.source is open in the ide running on the background.

Results:
           1.        2.         3.
Ubuntu   12:18     12:49      13:01
XP       28:39     39:02      40:15

It seems that most of the slowdown is caused just by IDE consuming some
resources and similar slowdown could be caused (and is) by any other memory
intensive process (ie. firefox with multiple tabs open) running on background.

Returning priority to P3.
