* You may want to cache and call the old function to allow multiple mods to
change knockback behavior.
* `minetest.forceload_block(pos[, transient])`
* `minetest.forceload_block(pos[, transient[, limit]])`
* forceloads the position `pos`.
* returns `true` if area could be forceloaded
* If `transient` is `false` or absent, the forceload will be persistent
(saved between server runs). If `true`, the forceload will be transient
(not saved between server runs).
* `limit` is an optional limit on the number of blocks that can be
forceloaded at once. If `limit` is negative, there is no limit. If it is
absent, the limit is the value of the setting `"max_forceloaded_blocks"`.
If the call would put the number of blocks over the limit, the call fails.
* `minetest.forceload_free_block(pos[, transient])`
* stops forceloading the position `pos`
