I don't believe the above is safe to say, yet. AFAICS, this has been discussed only on hackers (and patches) in this discussion, whereas this sort of change should probably be brought up on general as well to get a greater understanding of whether there are people who care. I expect that there won't be, but given that I'm still not sure what the plan to support applications upward is for this change, I think it's probably a good idea to query a larger segment of the population. ---------------------------(end of broadcast)--------------------------- TIP 1: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
