Sure, I mean the idea, not the actual existing code. Something simple as
sysmon_pswitch(9). Say

        struct sysmon_sleep {
                const char       *smpsl_name;
                void             *smpsl_arg;
                void            (*smpsl_func)(void *, int);
        };

        int     sysmon_sleep_register(struct sysmon_sleep *);
        int     sysmon_sleep_unregister(struct sysmon_sleep *);

And the smpsl::smpsl_func(arg, state) would be called from an ioctl, invoked
by the zzz(8) program.
