Btw. about half of those projects reason for existence owes to this "bug",
Emscripten http://emscripten.org , LLJS http://mbebenita.github.com/LLJS/ ,
Heap.coffee http://syg.github.com/heap.coffee/ , gl-matrix
https://github.com/toji/gl-matrix and that's OK

It's OK because the other half these projects owe it to array buffers to
make things run blazing fast, since the JIT in V8 enthusiastically
optimizes JS, the reduced pointer indirection speeds things up and the
better cache coherence helps a lot.
