+ * Language spec sez signal handlers take exactly one arg, even though we
+ * actually supply three. Ugh!
+ *
+ * We don't try to hide the difference by leaving out the args because
+ * that would cause warnings about conformant programs. Nonconformant
+ * programs can avoid the warnings by casting to (__sighandler_t *) or
+ * sig_t before calling signal() or assigning to sa_handler or sv_handler.
+ *
+ * The kernel should reverse the cast before calling the function. It
+ * has no way to do this, but on most machines 1-arg and 3-arg functions
+ * have the same calling protocol so there is no problem in practice.
+ * A bit in sa_flags could be used to specify the number of args.
