Background:</span>
<ul>
<li>
<spanclass="reference-text">On Windows, a sleep call can take 15 ms. This could potentially cause each Lua call to take 15 ms.</span>
</li>
<li>
<spanclass="reference-text">Some pages / templates will call Lua hundreds of times. (For example: the Weather Box on <ahref="http://en.wikipedia.org/wiki/Aruba"rel="nofollow"class="external free">http://en.wikipedia.org/wiki/Aruba</a> or the Citations on <ahref="http://en.wikipedia.org/wiki/Earth"rel="nofollow"class="external free">http://en.wikipedia.org/wiki/Earth</a> )</span>
</li>
<li>
<spanclass="reference-text">The busy wait is a primitive way to limit a wait to 1 ms (or less) before entering a more expensive sleep</span>
</li>
<li>
<spanclass="reference-text">A higher timeout busy wait value is more performant, but the disadvantage is that the UI will be locked up for longer</span>
</li>
</ul>
<dl>
<dd>
<spanclass="reference-text">For example, a busy wait of 250 means that the code will loop for 250 milliseconds before entering a sleep.</span>
</dd>
<dd>
<spanclass="reference-text">For sub-second values, this freezing will be unnoticeable</span>
