+ help
+ 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.
+
+ Choosing N saves about 250 bytes of code (on 32-bit x86).
