+.B \-\-merge\-core\-pages
+When platform support is present, provide hints to the operating
+system that identical pages may be shared between processes until they
+are written to. This can be useful to reduce the memory usage on
+systems with multiple SBCL processes started from similar but
+differently\-named core files, or from compressed cores. Without
+platform support, do nothing.

+.B \-\-default\-merge\-core\-pages
+Reverts the sharing hint policy to the default: only compressed cores
+trigger hinting. Uncompressed cores are mapped directly from the core
+file, which is usually enough to ensure sharing.
