SI-6412 alleviates leaks in toolboxes
Turns importer caches into fully weak hash maps, and also applies
manual cleanup to toolboxes every time they are used.
It's not enough, because reflection-mem-typecheck test is still leaking
at a rate of ~100kb per typecheck, but it's much better than it was before.
We'll fix the rest later, after 2.10.0-final.
