They said "6 staff-years". This means if they have 6 people working on it full time, it took 1 year to complete. If they had 60 people full time, it took just over 5 weeks (technically, i doubt that would work practically). >From speaking to a friend at sun, I do know it took a long time and a lot of effort, and was *not* a simple thing to implement. _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
