++ * Modified by rdh@yottayotta.com of Yotta Yotta Incorporated.
++ * 
++ * The code originally used mmap() to create a memory image of the new
++ * and old object files.  This had a few handy features: (1) you get
++ * to use a cool system call like mmap, (2) no need to explicitly
++ * write out the new file before the close, and (3) no swap space
++ * requirements.  Unfortunately, mmap() often fails to work with
++ * nfs-mounted file systems.
++ *
++ * So, instead of relying on the vm subsystem to do the file i/o for
++ * us, it's now done explicitly.  A buffer of the right size for the
++ * file is dynamically allocated, and either the old_name is read into
++ * it, or it is initialized with the correct new executable contents,
++ * and then written to new_name.
