Subject cvs commit: apr/file_io/unix mktemp.c open.c

  Modified:    .        CHANGES
               file_io/unix mktemp.c open.c
  Log:
  Even though it's not unusual for temporary files to be unlinked as soon as
  they're open on Unix, it makes the use of those files harder in some cases.
  For example, the filename we were getting back from apr_file_mktemp() was
  useless because the file had already been unlinked.  Now we defer the unlink
  until the file is actually closed.  This also makes the behavior on Unix
  somewhat more consistent with other platforms.

     *) Fix potential segfault when closing a file on Unix.  If
        apr_file_close() was called and it failed, it would not
