Ah, that'd probably the TCP connection timeout delay indeed. It'd be
the same with a faulty nfs mount on linux for instance. Having your
mounts directly in your home will always get such concerns, better make
yourself a ~/net directory.

Ftpfs should be taught the interrupt_operation protocol for C-c to be
immediate.

That completely depends on the situation you have.

If your network is really down (no route to the Internet), you'll get
an immediate "Network is unreachable" error. If your network is not
actually down (pfinet has an IP and a route, packets just don't get
answers), there is no real possibility for pfinet to know it but losing
patience after some timeout.
