#5 Large runs produce unusable output

[Tom Cook]

I've just run a large profiling run (took about five hours
to run). I excluded all the classes in the following
packages from the run:

java
com.sun
sun.
org.apache
org.xml
javax

The run completed without errors, but the java.prof file
seems to only contain the last 20 lines of the XML
output, which mostly consists of three empty threads
(not sure why they are there, but it's not much use to
me.) I'm not sure why this happens, and I don't really
have time to figure out just how long a run it takes by
trial and error.
