1. I have Yosemite and I1pro2, and 1.8.2
When I start to reading chart and press button on the device, I have to wait
up to 10 sec to hear the sound to start.
This turns out to be a problem with how OS X 10.9's "App Nap feature" works.
It seems to ignore the fact that chartread:
1) Is started by the user in a shell terminal.
2) Continues to interacting with the user via the shell terminal.
3) Has visible output to the user via the shell terminal
4) Is doing I/O to a USB device.
and starts inserting 10 second sleeps at random intervals
into chartreads execution, on the assumption that it is
somehow a "background process".
I'm investigating how I can correct App Nap's myopic view
of what constitutes "user facing" applications.
