   Love-Trowbridge recursive directory scanning algorithm:
 
         Step 1.  Start at initial directory foo.  Add watch.
 
         Step 2.  Setup handlers for watch created in Step 1.
                  Specifically, ensure that a directory created
                  in foo will result in a handled CREATE_SUBDIR
                  event.
 
         Step 3.  Read the contents of foo.
 
         Step 4.  For each subdirectory of foo read in step 3, repeat
                  step 1.
 
         Step 5.  For any CREATE_SUBDIR event on bar, if a watch is
                  not yet created on bar, repeat step 1 on bar.
