here on an old sun:

SunOS archiv 5.4 Generic_101945-32 sun4m sparc
tonys script prints one star, after a few (5-10) seconds top output
looks like this:

i then had to stop the experiment; we need that machine and it is
overloaded anyway ;)
on my linux box the test script printed 131 stars (54 in a second
run) then stops with two python threads eating all the cpu (x86 linux,
kernel 2.2.14)
we have some hpux machines here also but getting python w/ threading
to compile there seems a little difficult.
