I am trying to debug a bokeh server app. Currently I am working with pdb but I am not able to quit the python debugger. I get an error message when running the "q" command.

I am currently just using this to circumvent the issue, but that is not really a convenient solution.

import signal; import os; os.kill(os.getpid(), signal.SIGKILL)

Thanks for the help!
I have experienced this with other async and network apps. I always just ctrl-D until it eventually exits. The only other suggestion I can think of is a "hard" exit:
import os; os._exit(0) # notice the underscore
