Limit the MPD input buffer to less than the available memory.

It does work in that it will get the whole of a track into memory at track change rather than get it in chunks as needed throughout the playback.

How does it behave when you have a whole rip in one flac and the tracks are just delimited with a CUE sheet?
Does it load the single FLAC chunk defining the track, or ill it attempt to load the whole FLAC at once?
