Some ctstat options, such as ctstat -isam -i 60 1, print a line of statistics which are all zeros. This is because ctstat may not have accumulated significant statistics before the first row is printed.
A new option, -I (upper case i) has been added to allow for more meaningful values without changing the current behavior. It behaves the same as the -i (lower case) switch, except that it waits int seconds to provide time to accumulate significant statistics before returning the first row.
