Not all testing happens in batch mode.

(That is, the trampolines get written to /tmp, but can be deleted after loading.) Andrea Corallo writes: > That's your opinion and I respect it.

Like I said earlier, if anybody has a better name for the variable, renaming it is fine, but it has to be an improvement. > I have not said that once code is in master discussion is forbidden.

I don't see any advantages to doing that -- the changes that are in now seem to work fine for the stated use cases (which are both "don't write to $HOME while testing" and "I want to use a AOT-compiled Emacs, but don't do any further JIT compilation while running Emacs").
