Virtual memory is conceptually simple but potentially devastating to performance. Every memory access must go through segmentation (add segment base, check limit) and then paging (look up the page table). Naively, paging alone requires two additional memory reads per access -- one for the page directory entry, one for the page table entry.

But the triumphance of V3 is in the addSourceBuffer hook which solves a subtle problem. In earlier versions, hooking SourceBuffer.prototype.appendBuffer at the prototype level had a vulnerability in that if fermaw’s player cached a direct reference to appendBuffer before the hook was installed (i.e., const myAppend = sourceBuffer.appendBuffer; myAppend.call(sb, data)), the hook would never fire. The player would bypass the prototype entirely and call the original native function through its cached reference.
