+
+$details = "\
+This test creates a makefile where all depends on three rules
+which contain the same body. Each rule checks for the existence
+of a temporary file; if it exists an error is generated. If it
+doesn't exist then it is created, the rule sleeps, then deletes
+the temp file again. Thus if any of the rules are run in
+parallel the test will fail. When make is called in this test,
+it is given the -l option with a value of 0.0001. This ensures
+that the load will be above this number and make will therefore
+decide that it cannot run more than one job even though -j 4 was
+also specified on the command line.";
