Doesn't the strict definition of QBSR require a thread to keep no references to shared data when it is in quiescent state, whereas epoch-based reclamation allows threads to simply retain no references to older versions of shared data when it advances its epoch?

I'm referring to the FIFO implementation. On the definition of QSBR though, frankly, I think the term gets overloaded in some of the more recent literature in this area. Both EBR and QSBR require that no hazardous references get carried over across "protected sections" (EBR is explicit read-side protected sections and in QSBR, across a quiescent point).
