That is not a freeze, AT ALL. The scp process is simply waiting on the ability
to send more. I don't know if it has timeouts by default, but that's a
limitation of scp instead of TCP or the OS. It should react to Ctrl+C and be
killable anyway. And the terminal application is not stuck.

If this is what you're alluding to, then it really is "working around poor
code". Just rewrite so that you don't use blocking network writes or you do
enable SO_SNDTIMEO.

I was talking about when the kernel freezes, such as when a kernel thread
oopses.
