Mercurial reads the entire file into RAM when working on it- catting out,  
merging, etc.  It won't hold it any other time.  There may be edge cases  
around merging that could use more RAM than normal.  But unless you have  
an old computer, are dealing with 100MB files checked in occasionally or  
smaller files more often, I wouldn't worry too much.  You can get an idea  
of how much space is used by checking the size of .hg/store.  With  
largefiles and lfs, that actually uses more disk space because they are  
stored externally, and uncompressed.
