I have a love-hate relationship with GMail, sorry.
I am wondering if we are not correctly handling the case where we get
a shutdown request while we are still in the PM_STARTUP state. It
looks like we might go ahead and switch to PM_RECOVERY and then
PM_RECOVERY_CONSISTENT without noticing the shutdown. There is some
logic to handle the shutdown when the startup process exits, but if
the startup process never exits it looks like we might get stuck.
