Large form post data causes unstoppable memory growth and crash

The example above is not from me, but from someone else that is also experiencing the same problem http://chrisbosco.com/proto/safari/

An HTML5 Canvas element creates very large data strings when submitting in a form using mycanvas.toDataURL(). Other browsers submit large form post data properly, but Mac Safari, Mac Chrome, iOS Safari (iPhone & iPad) causes huge memory growth. Post data around 500KB makes the browser spike to >600MB of memory and become completely unresponsive (iOS browsers crash). The server does receive the connection and some of the data.
