+# In glibc (checked version 2.7), inet_ntoa allocates an 18-byte
+# per-thread static buffer for the return value. That memory is freed
+# at thread exit, however if called from the main thread, Valgrind
+# does not see the free (test main.no-threads).
+#
+# Since inet_ntoa() does not allocate memory dynamically per-call, this
