header MICRO -> SYS header -> defined header -> define MICRO --> struct --> function
implement by timewheel. problem: without execute timeout check, execute over duration check.
implement use pthread.
problem: use pthread_barrier_t which some problem on mac os.
implement by epoll. problme: others multi io not support like "select/poll/keque".
implement use binary protocl just lick |type|magic|len|pay_load|. simple to scala.
like sds library, but more simple.
smalloc use the memory like system, with a head metric message on memory head and with monitor.
- all is simple
- all implement by self
- cannot build on mac os which not support pthread_barrier_t
