Timestretch uses several buffers (totalling about 28k), but none of them are
used for the input data. Also they are only allocated when the feature is
explicitly enabled, so as not to waste RAM for people who don't want to use
the feature. The downside is that an explicit "enable" setting is required
and that a a reboot is needed after this is enabled.
