* Raise SIGALRM every 1.5s:
*
* CHECK_NE(-1, sigaction(SIGALRM,
* &(struct sigaction){.sa_sigaction = missingno},
* NULL));
* CHECK_NE(-1, setitimer(ITIMER_REAL,
* &(const struct itimerval){{1, 500000}, {1, 500000}},
* NULL));
* CHECK_NE(-1, sigaction(SIGALRM,
* &(struct sigaction){.sa_sigaction = missingno},
* NULL));
* CHECK_NE(-1, setitimer(ITIMER_REAL,
* &(const struct itimerval){{1, 500000},
* {1, 500000}},
* NULL));
*
* Set single-shot 50ms timer callback to interrupt laggy connect():
*
* CHECK_NE(-1, sigaction(SIGALRM,
* &(struct sigaction){.sa_sigaction = missingno,
* .sa_flags = SA_RESETHAND},
* NULL));
* CHECK_NE(-1, setitimer(ITIMER_REAL,
* &(const struct itimerval){{0, 0}, {0, 50000}},
* NULL));
* if (connect(...) == -1 && errno == EINTR) { ... }
* CHECK_NE(-1, sigaction(SIGALRM,
* &(struct sigaction){.sa_sigaction = missingno,
* .sa_flags = SA_RESETHAND},
* NULL));
* CHECK_NE(-1, setitimer(ITIMER_REAL,
* &(const struct itimerval){{0, 0}, {0, 50000}},
* NULL));
* if (connect(...) == -1 && errno == EINTR) { ... }
*
* Disarm timer:
*
* CHECK_NE(-1, setitimer(ITIMER_REAL, &(const struct itimerval){0}, NULL));
* CHECK_NE(-1, setitimer(ITIMER_REAL, &(const struct itimerval){0}, NULL));
*
* Be sure to check for EINTR on your i/o calls, for best low latency.
