FWIW, I am still seeing this myself.  Running ActiveSync on a good-old  
Original Droid.  My IMAP logs look like this:

...and so on.

And:

slusarz at bigworm % sudo ./horde-active-sessions
1696

But IIRC, this is the whole point of Bug #9733.  So maybe I should  
just shut up and wait patiently for Horde 4.1.
