I've seen this bug:
http://emacs.1067599.n5.nabble.com/bug-17168-24-3-50-Segfault-at-mark-object-td319032.html
I'm not sure if it's related to what I'm seeing. If I remove all
`clear-transient-map' from my pre-command-hook, they come back in
quick order.

That's weird. Do you see any strange message in *Messages*?

Helm is using `set-transient-map' a lot and it seems `set-transient-map'
doesn't remove properly its `clearfun' from `pre-command-hook' or more
exactly the `clearfun' doesn't remove itself from `pre-command-hook'.
So the many entries found in `pre-command-hook' may come from this.
BTW `set-transient-map' description in info is not accorded to its
docstring.

Clearly, that's what we see, but the question is "why". The code does do
(remove-hook 'pre-command-hook clearfun)
so why is this code not run?
Maybe it's because of the new condition:
((not (eq map (cadr overriding-terminal-local-map)))
;; There's presumably some other transient-map in
;; effect. Wait for that one to terminate before we
;; remove ourselves.
;; For example, if isearch and C-u both use transient
;; maps, then the lifetime of the C-u should be nested
;; within isearch's, so the pre-command-hook of
;; isearch should be suspended during the C-u one so
;; we don't exit isearch just because we hit 1 after
;; C-u and that 1 exits isearch whereas it doesn't
;; exit C-u.
t)
IOW, could it be that Helm keeps adding new transient-maps, rather than
follow the usual "nesting" of transient maps?
