>... why a high-value resistor (3.9M) is shunted across the diodes?  Does it
affect recovery?

Apart from any static discharge concerns, I think the main purpose is to
function as equalizing resistors to ensure that equal voltage is impressed
onto each diode -- similar to the need when older power supply rectifiers
also needed them.  It's just an uneducated hunch tho...
