In my case, I keep all the keys and [other sensitive data] on a partition that's created with a random key at boot time. If the machine dies, the keys and messages are lost but, such is the reliability of Debian, this hasn't happened yet. I probably reboot about once a year on average and have to remember to take copies of these files prior to doing it.

For Tor specifically, you can shred/delete the keys from disk completely, and only retain the copy in memory.
