On debian testing:
- start Pd with no jackd running
- jackd will be started by Pd
- Quit Pd (with ctrl-q, from menu, by closing window)
- Pd hangs with "watchdog: signaling pd..."
If you do a:
killall -9 jackd that also kills Pd
This does not happen if jackd was previously started and Pd connects to it.
jackd is version 1.9.9
