Yes. Yes, I was. Actually, I've done it several times.
The first time I did it, I was't sure it would work. But it did. :-)

I thought of that too late (worked for me in the past too)

On experimenting...
.. I discover that this works - against my expectations.
Conclusion? eth0 isn't going down properly.
If it went down, you wouldn't be connected any more.

I disagree on your analysis.
I think that sshd is holding onto state despite the network device vanishing. However, the down/up restores the network device long before sshd decides to discard the session. After all, an ifdown does make the device "not exist" as eth0: its IP address is not bindable, the routes are removed, etc etc.
It might also be the OS leaving the connection open *as far as the sshd process is concerned* although I'm sure it would get copious errors were it to try to use it whilst the device was disabled.

Re: I disagree on your analysis.
If sockets are open and working, then the interface ain't down.

This is how I handle the issue
I often will do "nohup /etc/init.d/network restart".
I lose my connection but the process keeps going due to the nohup.

Ar, that's what I do
Of course, if summat breaks you're knackered, but hell, exercise is good for you.

Nope, I disagree.
The interface goes down.
SSH server buffers the requests until it can get back through. As long as the tunnel construction hasn't failed it should still be there... It is sort of like pushing stop on your DVD once. When you remove and re-insert the DVD, the DVD Player starts exactly where left off.
It is the same idea, just implemented in Network protocol. Of course Timeouts apply with SSH but the DVD only fails when power has been removed.

It works like that with warp, too
I've done that particular trick on the box in the basement before.
