--- Comment #11 from Luboš Luňák <l.lunak at collabora.com> ---
I've run the steps to reproduce in Heaptrack and as far as I can tell there's
no significant memory leak. The problem appears to be that we do a huge number
of small allocations, which means glibc has to allocate a lot of system memory,
then when freeing that memory gets fragmented, so there's apparently no good
way to return it to the system. I don't think there's a reasonably simple
solution to this.
