To avoid leaking slots, `fetchRemove` must increment `available` (when the "fetch" succeeds).
Without the `available += 1`, the added test `"std.hash_map repeat fetchRemove"` fails with
run test std-x86-linux-none-Debug: error: thread 432734 panic: integer overflow
.../zig/lib/std/hash_map.zig:1365:28: 0x6471d5 in getOrPutAssumeCapacityAdapted__anon_47495 (test)
self.available -= 1;

Alternatively, `fetchRemove` could call `removeByIndex`, though that would entail calling `header()` twice instead of once.
