rec_close.c: Removed usage of munmap() method.

Note that there is a define MMAP_NOT_AVAILABLE that when NOT
defined results in mmap not being called but munmap is still
called.  A comment was also added to our notes about this.

+The MMAP_NOT_AVAILABLE define is inverted on its usage.  When it is
+defined the mmap method is called. Additionally, it is not used 
+thoroughly. It is not used in the unmap portion of the source.
