Yes, it can crash pd. I think if you close a patch with
a k_jackd~ object, without first closing the jack program, you
crash pd, and lose shared memory into void. I have fixed that
bug for a very long time a go, but
not released the code. But besides from that, and your client
works okey, it should work quite okey.
You have to manually delete all files in ~/.k_jack/ each time before
starting pd though. Eh, and you must close each patch window before
exiting pd to avoid losing shared mem.

Anyway, k_jackd~ is a hack and not at  all an optimal solution.
Its performance is quite optimal though, as long as you dont
want to route audio here and thre.

The optimal solution is a nonblocking callback-based jackified pd.
