PATCHES PROPOSED TO BACKPORT FROM TRUNK:

  [ New proposals should be added at the end of the list ]

  * mpm worker/mpm event: Revert an old (~10yr) change to the fd Q; move back to

    FIFO rather than LIFO, for more consistent performance

    so that older requests don't suffer

    Trunk patch (applies for worker): http://svn.apache.org/viewvc?view=revision&revision=1064269

    2.2.x patch (for event): http://people.apache.org/~igalic/patches/event-mpm-fdqueue.patch

  * mod_cache: Realign the cache_quick_handler() to behave identically

    to the default_handler() when reacting to errors when writing to the

    filter stack. Stops APR errors appearing in access_log as result codes.
