share mode locks on directories

[Tim Prouty]

Hi Jeremy,

I was talking to Volker earlier today about share mode locks on  
directories, and he said that you may be able to answer some of my  
questions, since you wrote the most of this code.  Do you have any  
examples of where it is important to take share mode lock on a  
directory?  I'm looking at all of the callers of open_directory(),  
and so far the close_file() is called on the dir's fsp before the  
calling function returns.  Is it purely for delete on close semantics?

Thanks!

-Tim
