+# This test would fail on solaris2.7 with tail from pre-1.22k textutils.
+# The problem was that using the solaris2.7 setvbuf function to turn off
+# buffering doesn't flush stdout.
+
+# FIXME: actually, I couldn't find a way to write the test (without resorting
+# to use of expect) so that it would provoke the failure on solaris2.7.
+# To exercise the bug, cat's stdout seems to have to be directed
+# to a terminal.
