* Forces any updates to this channel's file to be written to the storage
* device that contains it.

* <p> If this channel's file resides on a local storage device then when
* this method returns it is guaranteed that all changes made to the file
* since this channel was created, or since this method was last invoked,
* will have been written to that device. This is useful for ensuring that
* critical information is not lost in the event of a system crash.
