When you have an Internet connection that dumps you after 5 hours, you'll think otherwise. As soon as I get dumped, I have it set to redial back the University. Once the PPP is restablished, all of my connections are still there. If I haven't typed anything on them since I was cut off, they have no delay getting back. If I did type something, there's up to a 2 minute delay (though typically only a few seconds) to get my connection working again. If I don't get the same IP address (90% of the time I get the same one), then obviously my connections don't work but it is _very_ handy to not be disconnected. So here, a limit would only hurt things. It takes ~40-50 seconds to reestablish the PPP connection.
Windows immediately cuts me off from everything when that happens. Linux will happily resume a three hour FTP transfer after I've long fallen asleep.
