Subject: [PATCH] Valgrind fix: Clear struct kevent before checking for OSX
 bug.

William's original commit message:

   Valgrind complains on startup because kq_init passes to kevent only
   a partially initialized structure. The code doesn't expect kevent
   to look at .fflags, .udata, or .data, I suppose, because it merely
   tickles the kernel looking for an error response. But perhaps
   that's unwarranted chuminess (notwithstanding that it's checking
   for an OS X bug), and needless noise nonetheless.
