[Speex-dev] near and talk suppressed

I have now investigated further why the leak_estimate increases when near end is talking for a longer
time. What happens is that the accumulated crosscorrelation of y (Pyy) in mdf.c is decreasing towards
zero. The leak_estimate is calculated as the divistion of Pee with Pyy and when Pyy is close to zero
the output will dramaticily increase.
At least in my application there is need of handeling this behaviour. Have anyone else seen this behaviour
in your application?
One idea I have is to add a constant or floor to Pyy in the divisoin. Does anyone have any other ideas?
