> When using speculative execution, web interface can show inconsistent numbers and status.
> E.g. both speculative executed tasks as SUCCEEDED in taskDetails.jsp:
> Task Attempts	Machine	Status	Progress	Start Time 	Finish Time	Errors	Task Logs	Counters
> task_0005_m_000246_0	fwm521057.inktomisearch.com	SUCCEEDED	100.00%	6-Jul-2007 18:27:10
6-Jul-2007 18:31:36 (4mins, 26sec) 
> task_0005_m_000246_1	fwm521107.inktomisearch.com	SUCCEEDED	100.00%	6-Jul-2007 18:28:07

> or in jobDetails.jsp the number of completed tasks does not match the total number of
tasks even after the job has finished.
