[WebStorage] Property enumeration and checking presence

[Nikunj R. Mehta]

There is a requirement to obtain the storage mutex prior to performing  
Storage interface operations on the localStorage DOM attribute.

Section 3.4 asks for obtaining the storage mutex during property  
enumeration, although this term is not used anywhere else in the  
document. Similarly, it is not clear what is meant by "when checking  
for the presence of a property" that is any different from the  
getItem() method.

Please clarify.
