Are there any real risks to continuous polling?
<p>It's sort of been 'against my religion' to poll a condition using a <code>timeOut</code> or similar technique. I'd so much rather handle an event than continuously search for evidence that an event occurred.</p>

<p>But, due to spotty support for the <code>onHashChange</code> event, it was suggested I use a plugin that polls the <code>window.location</code> property every 50ms.</p>

<p>Are there any real risks to doing this (eg processing expense)? Or am I just superstitious?</p>
