flyingchanges - starting with the 757/767 (which was in initial design at the time of the 737 crash), the T/R is designed for this scenario. Depending on the model, all current Boeing aircraft have one of two basic systems that will keep the isolation valve open if the reverser isn't stowed.
Unfortunately, it was a malfunction of that 'restow' system that lead to the Lauda deployment (the third lock system that was added after Lauda is to prevent a recurrence of that scenario).
