+         This option causes module loading code to try to mmap
+         module first. If it does not work (for example,
+         it does not work for compressed modules), module will be read
+         (and unpacked if needed) into a memory block allocated by malloc.
+
+         The only case when mmap works but malloc does not is when
+         you are trying to load a big module on a very memory-constrained
+         machine. Malloc will momentarily need 2x as much memory as mmap.
