 The coend is not an exact functor, so the exactness of the triangle breaks.
 \item The obvious solution to this problem is to replace the coend with its derived counterpart.

+This presumably works fine for $S^1\times B^3$ (the answer being the Hochschild homology
 of an appropriate bimodule), but for more complicated 4-manifolds this leaves much to be desired.
 If we build our manifold up via a handle decomposition, the computation
 would be a sequence of derived coends.
