Alexey Goncharuk commented on IGNITE-10011:
-------------------------------------------
The second source of the "leak" is having multiple {{Stripe}}s per bucket. In
this case, a page is returned to a different stripe compared to the one it was
borrowed. In the long run it stabilizes.
This can be confirmed either by setting IGNITE_PAGES_LIST_STRIPES_PER_BUCKET=1
or changing {{removeAll}} to element-by-element remove (removes multithreading).
