-RecordReader Progress Reporting.

I'd like to get some idea on how the task scheduler relies on RecordReader.getProgress() with version 0.20.2.
There are times when I don't have an accurate count of the total records to be processed, and I wonder the impact on task scheduling when returning an inaccurate progress percentage. I found that when I return either 0 when not done and 1 when done will make the job hang.
Any advice is greatly appreciated.
