Err, it's the longest that *we* think the path can be.. That's not the
same as actually being the longest that a path can be, which depends on
the filesystem and OS... It's not hard to get past our 1024 limit:
sfrost@beorn:/really/long/path> echo $PWD | wc -c
1409

We shouldn't blow up in that case either, really.
Thanks,
