Doc from org.lwjgl.system.jemalloc.ExtentDallocI.invoke. Extent deallocation hook. An extent deallocation function conforms to the `extent_dalloc_t` type and deallocates an extent at given `addr` and `size` with `committed`/decommited memory as indicated, on behalf of arena `arena_ind`, returning false upon success. If the function returns true, this indicates opt-out from deallocation; the virtual memory mapping associated with the extent remains mapped, in the same commit state, and available for future use, in which case it will be automatically retained for later reuse.
