+    DArena arena = DArena::map(ArenaConfig { .size_ = 64*1024; });
+
+    cout << arena.lo() << ".." << arena.hi();
+
+This determines a VM memory address range.
+Actually address range is rounded up to a whole number of VM pages.
+Size here is a hard maximum. It cannot be changed for this arena instance.

+    arena.reserved(); // 64k
+    arena.committed(); // 0k
+    arena.available(); // 0k
+
+Although we know the address range for arena, it doesn't own any physical
+memory yet.

 xo-alloc2 documentation
 =======================
 
-xo-alloc2 is intended to provide fast vm-aware arena allocation.
-Next-generation version of xo-alloc.
+xo-alloc2 provides:
 
-Features:
+* Fast vm-aware arena allocation.
+* Allocates uncommitted virtual memory, and commits on demand.
+* When available, uses THP (Transparent Huge Pages) to mitigate pagetable pressure.
+* Optional GC support, with per-alloc header.
 
-* allocates uncommitted virtual memory, and commits on demand.
-* uses THP (Transparent Huge Pages) when available.
+Diagnostic features:
+
+* with alloc headers: forward iterators over individual allocations
+* configurable guard memory between allocations.
