Why not have 'nil' mean the same thing here that it does elsewhere for
Emacs time values, namely, the current time? (That would make the code a
tiny bit faster. :-)

2 billion would be safer, to cater to (hypothetical and non-POSIX)
implementations that represent leap seconds with 1 billion <= tv_nsec <
2 billion. That's what timespec_cmp does, anyway.

This test will fail to be out of range on (hypothetical) machines where
time_t is 128 bits. How about 1.0e+INF instead? You can test -1.0e+INF
and 0.0e+NaN while you're at it.
