If you use timers, then the interpreter maintains a list of all timers, and knows how long it should wait before the next timer must be raised. If the interpreter must wait more than 10 ms, then he sleeps inside the select() system call. If he must wait less than 10 ms, then he enters a busy loop that takes 100% CPU before doing the select() system call once with a timeout of zero. Otherwise, if you don't use timers, you can use: - The WAIT instruction. This instruction runs an event loop, so you have the same behaviour as above. - The SLEEP instruction, which uses the nanosleep() system call. At the moment, SLEEP does not do busy loops for very small delays. This may change in the future, in Gambas 3.
