Subject: [PATCH] darwin, freebsd: use ioctl(FIOCLEX) and ioctl(FIONBIO)

Set the non-blocking and close-on-exec flags with ioctl() instead of fcntl(),
it's about 10-25% faster.

Stick with fcntl() on Solaris. ioctl(FIONBIO) works but is twice as slow as
fcntl(O_NONBLOCK). ioctl(FIOCLEX) doesn't raise an error but doesn't actually
work either.
