Because it reduces performance significantly. If I remember correctly,
UMTS devices (u3g, etc) have big buffer sizes. This means that we have
to zero a lot of memory.

The code was already present, but not enabled, so I thought it would
have been better to at least offer it as an easy to enable feature.
