By 'memory locks', Jayson means mlock(). Unfortunately this is not really enough: you can mlock(), sure, but detecting that the page is still locked in is hard. Neither munlock() nor mlock() error if asked to act on an already-locked page, and the only way to see if it is still locked (or if anything is still locked) or even paged in is to consult things in /proc/$pid/ -- and if you had access to that, you could reseed more conventionally.

I don't see how you could make this work.
