That works for me. I'm using a series of python blocks to create org tables to
be inserted in specific places in the document. So each block is named for that
reason.
Do we need to worry about the note about not appropriate for large blocks of
code or does that not apply in this case with the way you implemented it.
(org-babel-comint-wait-for-output BUFFER)
Wait until output arrives from BUFFER.
Note: this is only safe when waiting for the result of a single
statement (not large blocks of code).
