Can I have another scenario?

User is waiting for important call, phone in his pocket, expecting it
to ring. Firmware crashes, reboots... and asks for a PIN.

When the important call comes, phone is not available... as it is
waiting for PIN...

I believe even pretty old Nokia's did cache the PIN so .. exactly this
did not happen.
