alt Hacker NewsI agree. I almost feel like this should be like a flag in `free`. Like if you pass in 1 or something as a second argument (or maybe a `free_safe` function or something), it will automatically `memset` whatever it's freeing with 0's, and then do the normal freeing.
Alternatively, just make free do that by default, adding a fast_and_furious_free which doesn't do it, for the few hotspots where that tiny bit of performance is actually needed.
