I ran a test with a similar open.

But to test it I used 'accept' and at that point my usage jumped to 
about 98% to 103% (of a possible 200% with two processors).  The open 
did not add more usage that I could tell.

Then I closed the accept, leaving the connection open.  It stayed up 
near 100%.  When I close from the passive (server) end, Revolution 
usage drops to almost 0.

It looks like a bad thread is running when any socket is open.  It 
might be polling.

This looks like bugzilla food to me.

I'm on OS X 10.3.4 with dual 1.25 GHz processors.

Oh, don't test using a default button.  For me, that causes usage to 
jump up 27%.
