Java and ps - NPTL?

[Brian Krahmer]

The 'time' command does show the correct results.  Top shows the system-wide
values correctly (third line down, showing user, system, nice, etc.)
However, the processing time for the java process listed in top will be the
same as ps.

I wrote a very simple test program which exposes the problem perfectly.  If
I do a lot of processing in the main thread, top and ps will show it at 98%
of the cpu.  If I kick up 8 threads which do a lot of processing and simply
join() them from the main thread, ps and top will show 0.0%, but top's
system field will go to 98%.
