    gcore - Fix /proc map reading, add verbose option, add limit option
    
    * Our /proc/*/map code allows incremental reads so the old
      code that detects an insufficient buffer size no longer works.
      Fix the code so processes with long maps are properly processed.
    
    * Add -v to verbosely print the segments being dumped.
    
    * Add -l <limit>{,k,m,g,t} to ignore segments larger than the
      specified limitm.
