I guess I'd prefer that we come closer to a clear resolution on the
question of the tv_nsec type before deciding.  If we're going to stick to
the existing POSIX spec where tv_nsec must be 'long int', then there is no
purpose to __snseconds_t but obfuscation.

But if everyone is agreed that departing from POSIX here, or having POSIX
changed, is a somewhat likely outcome, then the change can go in.


Thanks,
