-- attempted setting non-blocking send sockets with fcntl--improved speed, but got garbled images on workstation end...maybe need to adapt recv calls?
-- UDP (DGRAM) sockets might be a possibility, but would require a complete refiguring of the send/receive code.
-- ***Got framerate to ~8 f/s/c (close to rate at which cameras produce) by 1) changing save location on seykhl to /aux vice /home, and 2) changing pano cam to 640x480 greyscale.   If pano cam stays at 1240x934 color, framerate ~4.75 f/s/c
-- Removed g_multi.ko load from gpio-monitor.sh and added it to g-multi.sh with priority 01
