+`setitimer()`, called by `alarm()` when setting a new alarm, it is not able
+to disable on its own the timer when the alarm is fired the first time.
+On the other hand, manually invoking `alarm(0)` can cancel the running timer
+for `SIGALRM`.
+
+See also the attached file: on other OSes (e.g. Linux) it blocks waiting
+for a signal, while on GNU/Hurd it gets a new alarm and exits.

+`faccessat()` fails on some cases; in particular when:
+
+* flags does not have `AT_EACCESS`
+* dirfd is not `AT_FDCWD`
+* pathname is not an absolute path
+
+In such case, it will return -1 setting `ENOTSUP` as errno.
