Given that a time_t is also a signed 32-bit integer and 68 years exist
between 1970 and 2038, this means you can commit every second for the
next 68 years and not run out of revisions.

But beyond that: our code uses a custom 'svn_revnum_t' type, which we
can define to be whatever we want in the future. We're thinking,
actually, of switching all our revision "numbers" to arbitrary hex
strings soon. Just to stop people from thinking that it means
anything important about their project. :-)
