Hi,

Are there any ideas why traceroute requires waittime >=2 seconds?  The
only place it used is select(2) timeout.

In traceroute utility, minimal time to wait for reply is 2 seconds.
That's annoying, because system administrators often need traceroute
to skip hosts that do not respond faster, but when specifying obvious
wait time as 1 sec, they get an error. I see no reason for minimal
wait time to be 2 sec, the patch attached lowers limit to well
expected 1 second.
>How-To-Repeat:
1) traceroute -w1 somehost
traceroute: wait time must be > 1
2) ?!
