I'm 4'11 and have the same problem re top tube length, even with my titch 43cm roadbike. Had to change to a longer seatpost and get a compact handlebar, as recommended by Scherrit.
Now that I'm looking to get another bike, Islabikes (Luath small) seem a likely (the only?) option although I may try a Surly LHT or a Crosscheck in their smallest size (44cm) just for the hell of it. It would also be helpful if shorter cranks were more widely available.
