Only in the case where you were attempting to search for a particular  
filename but couldn't do it because you didn't have search access to  
the directory. If you don't have search access, then how can you prove  
whether EACCES is more or less accurate than ENOENT for a case- 
sensitive filesystem?

In the current behaviour, drop-boxes are broken. You can't copy a file  
to a directory where you don't have search permissions.
