That said, i'm worried that `State` in these callbacks isn't necessarily equal to `C.getState()` (the latter, by the way, is always equal to the `CallEvent`'s `.getState()` - that's a relief, right?), so if you'll ever be in the mood to check that, that'd be great :)

Hmmm, I tried making this take a (`CallEvent`, `CheckerContext`), but it bloated the code for little gain, since every handler function would start with the retrieval of the state and the call expression. That said, I could cascade these down to `FreeMemAux`, `MallocMemAux`, etc, to also take this pair instead, but I'll be honest, I don't see point until something actually breaks.
