I tried

--8<---------------cut here---------------start------------->8---
#+BIND: org-latex-image-default-width ".3\\linewidth"
--8<---------------cut here---------------end--------------->8---

with no success in async mode, but it works in synchronous mode. I guess
I'll avoid async mode for now on, or use a set of different
org-export-async-init.el files for different files.

Nevertheless I think it would make sense to have a way to set some
variables during async export. According to the Org Manual:

--8<---------------cut here---------------start------------->8---
Emacs variables can become buffer-local during export by using the BIND
keyword.  Its syntax is ‘#+BIND: variable value’.  This is particularly
useful for in-buffer settings that cannot be changed using keywords.
--8<---------------cut here---------------end--------------->8---

But the options set using #+ keywords are used during async export while
those set using #+BIND are ignored. A "+BIND-ASYNC would come in handy.
