-<p>When a program requests a service, this service can be performed either <i>synchronously</i> or <i>asynchronously</i>. </p>
-<p>A synchronous service is the normal pattern for function calls where the
-function returns and the service requested has either performed successfully
-or has failed and an error code returned.</p>
-<p>An asynchronous service is <i>requested</i> by a function call but completion
-occurs later. Completion is indicated by a <i>signal</i>. Between the issue
-of the request and the signal, the request is said to be <i>pending</i>. The
-requesting program can do other processing while the request is pending or
-it can issue a <i>wait</i>. The operating system wakes the program up when
-completion of any of its pending requests is signalled.</p>
-<p>A program may contain a number of independently-executing units, called
-threads. All programs have a primary thread, and may create other threads,
-possibly for providing or using asynchronous services.</p>
-<p>If all threads are in a wait state, for example, waiting for user input,
-Symbian platform powers down as much as possible of the machine’s electronics.
-This results in battery savings and, consequently, a considerable extension
-of useful battery life.</p>
