Well....
(1) Fed doesn't care about nominal interest rate - they care about real interest rate. If real rate went from 1% to 4% then they may have to face a tough choice of another round - but chances are that increase is driven by better economic data. In which case, mission accomplished. No need for more purchases.
(2) They can - but they can also accomplish liquidity withdrawal via reverse repo. They can also raise fed funds rate.
(3) They can hold it to maturity and withdraw liquidity via the steps I outlined in (2). There no reason for their to have to face the dilemma of a large balancesheet or taking losses.
That said, there will surely be unforeseen side effects to all of this - but I don't think it'll be simple mechanical issues you raised.

Quote from benwm:
It's not clear what the exit strategy is here. Suppose 10 year yields back up another 1% to 4% in response to commodity inflation. Then what?
(1) Print more money to double, quadruple,..etc their bets for the greater good of homeowners.
(2) Withdraw liquidity to ward off inflation by selling off $1-2 Trillion of bond holdings at a loss?
(3) Sit on their bond holdings until maturity and leave all the newly created money in the system, running the risk of currency collapse and hyperinflation?
If long yields fall then no problem. But if not, which is it? (1), (2) or (3)?
