Out of interest, what sort of engineering effort is required to get
this working natively on AMD64?  From what I've read of your
descriptions of it in the past, it sounds like it'll be even harder
than with LuaJIT 1.

Unfortunately, using the 32-bit x86 version doesn't help when you
ideally want to link to a load of libraries that are 64-bit.  (We tend
to just not use LuaJIT on our web apps simply because the effort
required to keep two sets of libraries up-to-date and managed is more
than the performance benefit makes worth.)

If it's a matter of sponsorship and paying for your time, I wonder if
it might be worth starting a bounty pot.
