I actually relied for a while on the last choice. I had a remotely accessible root shell that never logged out. When things got sluggish, I was able to /bin/kill to my heart's content. It wasn't a pretty solution, but it kept me running until I was able to solve the problem properly.
Would this work without the OOB hardware? E.g. if I leave a detached screen'd SSH session open from another server, then ionice + nice that shell on the problem server?
I wouldn't rely on that setup.
In my case, the problem server was connected to a Digi console server via its serial port. On another (non-problematic server), I opened a screen session and connected to the console on the problem server. I had to adjust some timeouts here and there to ensure an eternal console. :-)
