low-end persistence strategies?

> John Lenton:
Also, if you use something where the process doesn't terminate between
calls (such as mod_python, I guess), you have to be sure to write the
try/finallys around your locking code, because the OS only cleans up
the lock when the process exits.

This is what I feared. What happens in the case of a power failure?
Am I left with locked files floating around?
