Hmmm...

        For 2.5, changing the timer interface to disallow mod_timer or
add_timer (equivalent) on self, and making the timerfn return num
jiffies to next run (0 = don't rerun) would solve this, right?
I don't see a maintainable way of solving this otherwise,

        Of course, kfree'ing the timer struct and returning non-zero
would be a *bug*...
