Should the federal courthouse doors be reopened to state prisoners?

Closed Doors - Should the federal courthouse doors be reopened to state prisoners, particularly those on death row, to ensure that justice is not short-circuited? Or should the federal courthouse doors remain as they are now, with only one federal review (unless the case presents an extraordinary issue)? Asked another way, where should the line be drawn between the interest of justice (ensuring that only the truly guilty are executed) and the need for finality (many of the habeas petitions raise issues that are unlikely to succeed)?
