     a newly created child; note that merely mixing a PID into the random 
     seed of a new child doesn't markedly increase entropy. [Sander Temme]

     IPv6 builds.  [Ivan Zhakov <ivan visualsvn.com>]

  *) Add new experimental configure option --enable-allocator-uses-mmap to
     use mmap instead of malloc in apr_allocator_alloc(). This greatly reduces
     memory fragmentation with malloc implementations (e.g. glibc) that
     don't handle allocationss of a page-size-multiples in an efficient way.
     It also makes apr_allocator_max_free_set() actually have some effect
     on such platforms. [Stefan Fritsch]

  *) configure: Support 64 and 32 bit universal builds for Darwin/
     OS X 10.6+. [Jim Jagielski]

     miscompile some brigade related code. PR 50190. [Stefan Fritsch]

  *) apr_file_flush_locked(): Handle short writes. [Stefan Fritsch]

  *) apr_pollset_create_ex(): Trap errors from pollset providers.
     PR 49094.  [Sami Tolvanen <sami.tolvanen mywot.com>]

     pipe when the pollset was created with APR_POLLSET_NOCOPY.
     [Neil Conway <nrc cs.berkeley.edu>]

  *) Fix detection of some Linux variants when configure is built with
     recent GNU tools.  [Eric Covener]

  *) Avoid a redundant fcntl() call in apr_file_open() where O_CLOEXEC
     is supported.  PR 48557.  [Joe Orton]

  *) Improve platform detection by updating config.guess and config.sub.
     [Rainer Jung]

Changes for APR 1.4.2

     the apr hash and table structures, reported to affect Subversion

     [Brane Čibej]

Changes for APR 1.4.0

     socket has been closed by the peer.

     Added apr_pollset_create_ex and apr_pollcb_create_ex that allows
     choosing non-default providers.
     [Mladen Turk]

  *) Win32: Use WSAPoll as default pollset method if supported and found
     inside winsock dll.  [Mladen Turk]

  *) apr_temp_dir_get() now checks the TMPDIR environment variable first,
     instead of third.  [Jim Jagielski]

  *) Add apr_file_sync() and apr_file_datasync() calls.  [Bojan Smojver]

  *) apr_pollset_wakeup() on Windows: Fix core caused by closing the
     file_socket_pipe with standard file_close. 
     [Arsen Chaloyan, Mladen Turk]

  *) Introduce apr_hash_do() for iterating over a hash table.  [Mladen Turk]

  *) Make sure WIN32 behaves the same as posix for file-backed shared memory 
     by removing the file on cleanup/remove.  [Mladen Turk]

     apr_pollset_poll() call.  [Mladen Turk]
