* This class contains a systemwide File creation time cache that persists these

*
* This class is needed because we don't want to consult
* File.lastModifiedTime() all the time. We want to preserve creation times
* across the Gnutella network.
*
* In order to be speedy, this class maintains two data structures - one for
* fast URN to creation time lookup, another for fast 'youngest' file lookup.
* <br>
* IMPLEMENTATION NOTES:
* The two data structures do not reflect each other's internal representation
* - specifically, the URN->Time lookup may have more URNs than the
* Time->URNSet lookup. This is a consequence of partial file sharing. It is
* the case that the URNs in the sets of the Time->URNSet lookup are a subset
* of the URNs in the URN->Time lookup. For more details, see addTime and
* commitTime.
*
* LOCKING: Note on grabbing the FM lock - if I ever do that, I first grab that
* lock before grabbing my lock. Please keep doing that as you add code.
