reduce task progress above 100%?

[pvvpr]

Hello,
  A strange thing happened in my job. In reduce phase, one of the tasks
status shows 101.44% complete and runs till some 102% and successfully
finished back to 100%. Is this a right behavior?

  I put a quick copy-paste of the web GUI reporting completion of the
tasks. (sorry for the bad formatting below).

thanks,
