[PD] midi input latency with Gem

I recall this problem from a few years ago, and that running Pd with
elevated priority made this worse.  FWIW, I found MIDI nearly
worthless as a 3D controller due to the 7 bit resolution.  Scaling
0..127 to rotation, translation or film scrubbing was not nearly
enough to offer decent control.

It's probably not going to be threaded very much either since calling
GL without a ton of sync glue code gets really ugly.  On OSX,
Quicktime really likes to run in the same thread, although many of the
codecs, compressors and video capture components spawn additional

Lucky for you I have extended this hack to allow sharing of pix_
chains between pd processes.
