That's not because it was called from external code.  It's because it
was called asynchronously.

What I meant by the above is that it's perfectly OK for module code to
call back Elisp in cases such as when Fmapcar calls Elisp:
synchronous calls.

There are indeed various restrictions about *when* you can run Elisp.
These apply to module code, but they also apply to core code.
