-# https://github.com/sbt/sbt/issues/3545
+# The tests/fork-parallel test will currently always 
+# report success when run on less than four cores,
+# rather than  failing in one of the two cases as expected.
+# TODO: Adjust this scripted test so that it works as
+# intended on less than four cores as well.
+
+# To debug, it is possible to limit the number of cores
+# reported to sbt, and run the test, by using:
+#   taskset 0x00000003 sbt 'scripted tests/fork-parallel'
+# See: https://github.com/sbt/sbt/issues/3545
+
+# This bit won't currently work when using less than four cores.
