Thank you Darlan,

I have just pushed a change that should make that better -- does that
improve things?

I did think there was something else going on (that was why I asked Tom
for confirmation), but I didn't have time to investigate properly. The
problem seems to be that, on a folded headline containing many blocks,
`org-edit-src-find-region-and-lang' is actually quite slow to come up
with the answer "No, there's nothing for me to edit here."  (try issuing
M-x org-edit-src-code on a folded headline containing many blocks; I
haven't understood this properly yet.)
