You know, in looking at this more closely, maybe you should take a stab at
modifying your data structures to better match the type of logic that needs to
be applied to them. Iterating over a wanna be FIFO queue is just not quite
right. I think you've managed to implement the desired behavior despite the
data structures, but they're not working in your favor.

struct CoordinationInfo {
  Q pendingTransactions;
  Set activeReadTransactions;
  Transaction* activeReadWriteTransaction;
};

That may be easier to reason about.
