Ah, thanks, and now I've remembered where I saw these: tenderlove's "Worst Ideas Ever" talk at rubyconf, where he and ryan davis basically try and run all this shit at the same time, so they're rescuing segfaults then fixing them using inline assembly, cross compiling rails 2.3's AST into XML and then executing it, cross compiling rails into PHP, and all sorts of awful shit. Hilarious.
