    If we want to support this in general, we must implement an async
    version of open-network-stream (or add an optional arg to it to make
    it async - that arg could be a function which is called when the
    connection has been opened.

Is it hanging in open-network-stream?  If so,
precisely where in open-network-stream is it waiting?
It may be a straightforward matter to implement quitting from
a few places where the waiting typically happens.
That would fix this problem.
