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.
Patch against 1.4.13-stable.
