Squid-2.2.STABLE3: Switch back to unlink instead of truncate
    Switch back to unlink instead of truncate when releasing cache files.
    There are some known problems with the use of truncate:
      * Very much increased inode usage (slightly more than doubled)
      * Additional race conditions when storing files, which theoretically
	can cause corrupted cache files if a file is reused while being
	truncated.
