> Side note is this memory failing to free behaviour observed on windows?

No idea, I only develop on linux. Looking at the the github issues, it seems 
people that had the issue were also using the linux version...so we can't 
conclude anything about windows

From what I observed, it (almost?) never fails to free memory, although 
sometimes it's only a few kB.
Anyway, are you suggesting to keep track of how many time we call `malloc_trim` 
and how many times it fails ? Or simply logging when it fails ?
