// * InitFromChannel and InitFromTransportSecurityInfo members
// * ResurrectInfoOnChannel member

// * constructors and assignment operators for this class.
// * DOM Cache schema code (in dom/cache/DBSchema.cpp) to ensure that the newly
// added member is saved into the DB and loaded from it properly.

// ResurrectInfoOnChannel() cannot be called on it before it has been
// initialized. There are assertions ensuring these invariants.
