Totally sucks. I coulda sold for a profit if it weren't for this supposed DTCC and their slow azz MO.
I get the feeling though that there's a cost behind the issuing shares of a new symbol and TDA (and other brokers) simply don't wanna pay it, waiting instead until the D comes back off, and it can be traded again just as before.
What a lesson learned! Worse than having a stock halted. At least a halt only lasts for 10 days. This looks like it'll be the full 20 days.
