[Click] Patch for Mac users

[Eddie Kohler]

Hi Alexander,

Going through very old mail ... Thanks for this bug report.  I think we've 
since fixed the bug, which was in Click's generic poll() handling.  If you 
know there are still problems, and don't hate us for the delay, just send a note.

Eddie
