[PD] pd-0.45 + jack == weirdness

[Miller Puckette]

Are you using 0.44?  (I don't think 0.45 exists yet :)

The only relevant thing I can find in recent commits is a change from
jack_client_new() to jack_client_open() back in 2010.

With apologies, here is the commit I found...

    properly handle shutdown of jackd and updated to new jack API
    
    in older versions of Pd, if the jackd shut down (e.g. because the user stopped
    it manually), Pd would just freeze and could not be revived (you have to KILL
    it)
    properly handling the jack_shutdown signal allows us to cleanup and continue to
    run. the user can then select another backend at their convenience.
    
    Pd's jack-backend mainly used _deprecated_ way of interfacing with jack (namely
    using jack_client_new() rather than jack_client_open())
    the new API allows more flexibility (e.g. the jackd need not run before the
    application starts -> if it is missing, it will be automatically launched)
    
    TODO: jack is actually a callback-based API...

Is it possible this bug has been there for the last three years? (i.e.
0.43 and 0.44 would have this problem)?

cheers
