Yes, and it's OK except that Jack should not do this
when the input and output are on the same client.

When connecting A to B the way the signal A is seen by
B must not depend on other ports being connected to B.
At least not if a writeable Jack port is supposed to
be a linear summing point. But when using zero-copy
in some cases it does. Which is why I *do* call this
a bug. Apparently it has not been fixed.

Ciao,
