[PATCH 6/9] dsnoop: The stop threshold was not implemented correctly

[Mark Hills]

The previous implementation would mean that stop_threshold behaved
erratically. The intent is to detect that the buffer is too full,
and stop.

In practice, I don't think this was a bug in practice for applications
which don't adjust the stop_threshold. The line above catches those cases.
