I mean that while the network is being restarted, as a user, I would
expect the ongoing connections to wait for the network rather than
fail immediately.

In the present case, this was:

  Failed to open TCP connection to udd.debian.org:443 (getaddrinfo: Temporary failure in name resolution)

so the restart of the wifi network should be done in such a way
that getaddrinfo does not fail immediately.

But this is too late as I expect something in the terminal before
I quit aptitude.

But how-can-i-help could wait for the network to come back, though
something at the system level (what I requested above) would be
better, as all applications could benefit from it.
