Ah, it's been so long since I looked at all of this. There's actually TWO
erl.ini files! One in the top level bin, and another in the erts/bin folder.
Methinks that probably they have to agree if you're invoking from the top
level bin folder.

I tend to ignore the top level bin folder and invoke the exe's in the erts
folder instead. But I also pass in explicit config and boot options, so your
mileage may vary.

PS There's also some registry entries, but I've never quite understood what
they are for.
