I have a shell command in stuck in D state (imagine doing ls on a NFS share when the network is down).

How do I detach from such a command? I can't kill the process in any way (well, it's called "uninterruptible" for a reason), and ctrl-z does nothing, so I have no place to type detach.

Please don't propose workarounds (like "just open new terminal", "use screen/tmux", etc.), I know them, I'm just curious for a better solution =)

PS: This may be a duplicate, but all I was able to find is threads like "Q:ctrl-c does not work A: use kill-9"
