+ Implement a "per-job" output synchronization option.
+
+ * main.c (decode_output_sync_flags): Recognize the new option.
+ * makeint.h (OUTPUT_SYNC_JOB): Add new values for "job"
+ * job.c (assign_child_tempfiles): In per-job mode, truncate the
+ temp file for re-use by the next job.
+ (sync_output): Don't close the temp files as we may still use them.
+ (free_child): Close the temp files here as we definitely don't
+ need them.
+ (new_job): In per-job output mode, sync_output() after each job.
+ * job.h (struct child): Avoid ifdefs.
+ * make.1: Add new options to the man page.
+ * doc/make.texi (Parallel Output): Break documentation on input
+ and output into separate sections for readability. Document the
+ new "job" and "none" modes.
+
