I've got an issue with following code:

<code>
t.cmd('String' => "iptables -t mangle -L", 'Match' => /\#/, 'Timeout' =>
15 )
{ |c|

          print c
          sleep 1               #THIS IS AN ISSUE I CAN'T UNDERSTAND

          if c =~ patternDup    #patternDup is RegExp object
               rtrnMsg = "DUPLICATED"
               iptblsLog.info(c.to_s)
          elsif c =~ patternRules   #patternRules is RegExp object
               rtrnMsg = "RULES"
               iptblsLog.info(c.to_s)
          else
               rtrnMsg = "NO RULES"
               iptblsLog.info(c.to_s)
          end #if

}
</code>

Without sleep sometimes comparison c with particular RegExp doesn't
work. It isn't due to that regular expression doesn't match string
compared with.
After adding the sleep everything works well.

Please, help me to understand it. Why adding sleep resolved this issue.
Thanks in advance.
