Question: Does swissmap shrink on key deletion?

[Jakobovski]

Does swissmap suffer from the same key-deletion issue as golang map? Namely memory is not freed upon deleting of keys?

See golang/go#20135

I modified the example from this article: https://100go.co/28-maps-memory-leaks/

Go's Map:

After creating map:  0 MB
After adding 1 million elements:  461 MB
After deleting 1 million elements:  293 MB

Swiss:

After creating map:  0 MB
After adding 1 million elements:  411 MB
After deleting 1 million elements:  274 MB

Although in my quest for a memory efficient Map, I did find HaxMap

After creating map:  0 MB
After adding 1 million elements:  184 MB
After deleting 1 million elements:  16 MB
