[PD] cpu-load

[Bill Sack]

hello again,

the mystery continues ... when i start pd-0.35 with no midi (i.e.: not
specifying my usual midi device at -midiin[out]dev 2) then cpu-load is
comparable to pd-0.34 (0-3%) ... starting with midi it goes to ~30% even
before starting dac

midi interface is an old MPU-401 card using alsa mpu401 driver ... no
problems in pd-0.34

hmm
