calling jack_deactivate out of the process thread crashes

Hello,

I need a way to remove my client from of the process graph
in the next
cycle, called from the RT process function.

Calling jack_deactivate will zombify jackd. Is this a known
behavior
or did I something wrong? I am using 0.102.20.


So my RFE:
jackd should evaluate the return value of the clients
JackProcessCallback function and follow a clients deactivate
request.


kind regards
Daniel Schmitt

jack_deactivate() is not a realtime-safe operation and must
not be
called from the process() callback.  So, yes you did
something wrong.

A non-zero return value from process() should deactivate the
client.

It should but it doesn't. I tested it with 0.102.20. and
0.100.0.
Can someone confirm this?
Is it possible to include this in a future release?
