[uncomputable]

The program loads for multiple seconds when selected and for further seconds when run.

The hash loop is faster now, and in some browsers it takes than a second to run. I will keep this issue open, because we might switch the web IDE over to a frame-based Bit Machine like in rust-simplicity. A frame-based Bit Machine should be significantly faster than a function-based runtime.
