Oh, my. Here's what I get with 64-bit Hamilton C shell on Windows 7 on a 2.67GHz Core i7: 10 C% date +"%a %b %d %H:%M:%S %Z %Y" Sun Oct 10 12:03:31 PDT 2010 11 C% while (1) !!; end | uniq -c while ( 1 ) date +"%a %b %d %H:%M:%S %Z %Y" ; end | uniq -c 164 Sun Oct 10 12:03:51 PDT 2010 170 Sun Oct 10 12:03:52 PDT 2010 169 Sun Oct 10 12:03:53 PDT 2010 169 Sun Oct 10 12:03:54 PDT 2010 Here's what I get on a MacBook with a 2.4GHz Core 2 Duo, again running 64-bit code on Win7: 8 C% while ( 1 ) date +"%a %b %d %H:%M:%S %Z %Y" ; end | uniq -c 17 Sun Oct 10 12:17:21 PDT 2010 84 Sun Oct 10 12:17:22 PDT 2010 77 Sun Oct 10 12:17:23 PDT 2010 78 Sun Oct 10 12:17:24 PDT 2010 But this is running native, using threads instead of a fork emulation.
