-    * Anonymous-memory mmap over SYS_ALLOC. SYS_ALLOC returns
-    * page-aligned process memory, which is exactly what callers like
-    * GCC's page allocator need. File-backed mappings are not
-    * supported and fail with ENODEV.
+    * Demand-paged anonymous memory backed by the kernel's VMA subsystem.
+    * File-backed and shared mappings are not supported and fail cleanly.
