For the record:
This option was implemented to enforce a mouse polling rate of 62.5Hz which dramatically reduced the XWindow event system update rate in certain circumstances (oddball or "performance" mice can have update rates of 1000Hz, which is silly).
One possible side-effect of this is that some mice are designed badly and assume that the host system will always poll at exactly the requested update rate. This means they communicate position updates assuming a fixed time-delta between each sample. If you decrease that sample rate, the mouse starts to exhibit lag.
Rockets are loud.
