--- Comment #5 from Marc Ordinas i Llopis <marc...@wikimedia.org> ---
I did detect some amount of memory leakage while profiling locally, if I recall
correctly, ~90k per fetch/results cycle. As I mentioned in a previous comment,
the leakage seemed to come from not-released arrays of "code
deoptimization_data". If I remember correctly V8's arch that could come from
virtual method calls over many different implementations, debugging/profiling
artifacts, or a few other things. And of course it could be our code or some
library leaking closures, but I think those would show up differently,
especially if the code is used only once.

That's where profiling took me… I'm a little stumped of what to try next, but I
think that I'll make a small test case to check it's not the mysql library.
