/**
 * Checks if the copy in question can be disposed of, and if so, does it. A
 * copy can be discarded if it isnt noted by any user more than his or her
 * visible version of this file. To find this out, the entire map must be
 * searched below the original URI. This process can be parallelized very
 * well. If the copy can be disposed of, it must first be removed from the
 * map of up-to-date copies so that it will not be reissued during the
 * deletion, and then deleted. If the file cannot be deleted, a warning is
 * written to the logfile. System administrators should be on the lookout
 * for such alerts, because if they occur frequently, this could signal that
 * the partiton is filling up with temporary files. This can be a problem
 * especially on Windows, because the Java virtual machine occasionally has
 * problems deleting files here./*from w w w .j  av a 2s.co m*/
