Hello, the sleep(3) manpage states, under DESCRIPTION, that "sleep() makes the calling process sleep [...]". I believe this not to be true and the appropriate text would be: "sleep() makes the calling thread sleep [...]". I think in the past Linux did implement it so it would block the process, I am not sure. Anyway, sleep is currently implemented using nanosleep() and a simple threaded program can be written to prove sleep only sleeps the calling thread.
