So, contrary to your analysis, I don't think we leak cs->bcs.
You are right. Thanks that you pointed this source code place out again. I imagined that the exception handling implementation could be more direct somehow for a while. But this function takes extra care for data synchronisation by a mutex. Now I recognise also that this proposed update step "4" was inappropriate. I'm sorry for the confusion I introduced here.
