+	The default configuration for the network stack has been changed
+	such that it now runs without the Giant lock unless configured
+	otherwise.  If you experience network-related instability, you
+	may wish to try setting "debug.mpsafenet=0" or compiling the
+	kernel with "options NET_WITH_GIANT".  Details on the netperf
+	project may be found at:

 	PFIL_HOOKS are a fixed part of the network stack now and do not
 	need to be specified in the kernel configuration file anymore.
