2nd attempt at answering this, I'll take it more slowly this
time (my Netscape crashed at the end of the last reply :()

This is a Java problem.  What JVM are you using?  AFAIK there
is no busy waiting or polling or anything like that in WebFunds
itself, although there is some within Java, and there may be
some in Swing (it's not possible to really identify what is
in Swing or not...).

On my machine(s) (FreeBSD), the CPU consumes a little to run
WebFunds, but it is under the 0.01% limit that is required to
get a number.  But it is consuming a tiny amount, because I
can see it sort to the top of top, as it were.

However, on starting up, SecureRandom kicks in and throttles
the CPU for about half a minute trying to generate some numbers.
