The sine wave has a range of [-1 1].  I just meant sin^2 would touch and
not cross zero, which zerox doesn't catch.  Sorry for my confusion.  If 
you
want to catch sinosc with zerox, you might try the following:

   // patch
   sinosc s1 => gain g => dac;
   // feed s1 into g as second input
   s1 => g;
   // feed s1 to zerox then blackhole, which sucks samples but doesn't 
play them
   s1 => gain g2 => zerox z => blackhole;

I have updated the wiki with this method, which should be more robust 
and
concise.
