+
+       * log.c (redirect_output): Use unique_create to avoid a race
+       condition.
+
+       * mswindows.c (fake_fork_child): Use unique_create.
+
+       * utils.c (fopen_excl): New function that opens a stdio stream
+       with the O_EXCL flag (where available).

+       (fork_to_background): Use unique_create to create the file
+       immediately to avoid race condition with multiple instances of
+       wget -b.
