+       - Fixed some problems related to disk (and pipe) write error
+         handling.  file_close() doesn't always close the file
+         immediately; i.e. when there are pending buffers to write.
+         StoreEntry->lock_count could become zero while a write is
+         pending, then bad things happen during the callback.
+       - The file_write() callback data must now be in the callback
+         database (cbdata).  We now use the swapout_ctrl_t structure
+         for the callback data; it stays around for as long as we are
+         swapping out.
+       - Changed the way write errors are handled by diskHandleWrite.
+         If there is no callback function, now we exit with a fatal
+         message under the assumption that the file in question is a
+         log file or IPC pipe.  Otherwise, we flush all the pending
+         write buffers (so we don't see multiple repeated write errors
+         from the same descriptor) and let the upper layer decide how
+         to handle the failure.
+       - Fixed storeDirWriteCleanLogs.  A write failure was leaving
+         some empty swap.state files, even though it tells us that its
+         "not replacing the file."  Don't flush/rename logs which we
+         have prematurely closed due to write failures, indiciated by
+         fd[dirn] == -1.  Close these files LAST, not before
+         renaming.
+       - Fixed storeDirClean to clean directories in a more sensible
+         order, instead of the new "MONOTONIC" order for swap files.
