I confirm that the 2-second delay still strikes when using a
just-bootstrapped-from-"emacs-24" binary and running
src/emacs -nw -Q FILE.  I see the same output as above for "C-h l".

As mentioned above, it appears to be terminal specific,
striking only when using OS X's "Terminal".
The delay arises before the contents of the FILE is first displayed,
and can be skipped if you know to type a key during that short
interval.  For some initial discussion, see this thread:
