A globally unique ID, such as:

    "What filename should I store this page under?"

The standard library has (several versions of) similar functionality 
for temporary filenames.  They aren't all threadsafe, they often 
enforce the "temporary" aspect, they run into hashing collision 
problems eventually, there is no good way to include even approximate
ordering information, etc...

The fact that these are in the standard library suggests that it is a
common use case.  The fact that there are several different versions
each with their own problems suggests that the problem is hard enough
to justify putting a good solution in the library.
