[plt-scheme] file lock

Different file access modes are determined by the underlying OS.  MSWord 
actually works on copies of the file.  Emacs and vim both work on copies of 
the file and save different versions, with names like file~ or #file#, if 
multiple instances are being used or the program halts before saving.
