The profiler is the most hardware/operating system
dependent part of Eclipse because it uses a timer
sampling technique that interrupts the running program
every 10ms and tries to find out which predicate is

This is currently only implemented on SunOS4/5 and Linux.
The SunOS results are usually reliable, but we know that
on Linux we always seem to get a certain amount of faulty

There also seems to be a problem with time being reported
in the wrong built-ins since version 5.0.

We'll try to find some time to address these problems
in version 5.2 which is scheduled for release in May!
