+Subject: Work around MacOS 11.2 code page decommit failures
+
+MacOS 11.2 refuses to set "no access" permissions on memory that
+we previously used for JIT-compiled code. It is still unclear
+whether this is WAI on the part of the kernel. In the meantime,
+as a workaround, we use madvise(..., MADV_FREE_REUSABLE) instead
+of mprotect(..., NONE) when discarding code pages. This is inspired
+by what Chromium's gin platform does.
+
+Fixed: v8:11389
