Don't play hardcore on Mac with Parallels rebooting in the background

A tip for anyone as dumb as me.

Don't have a parallels windows vm, running in continuity mode, rebooting in the background while playing a hardcore character under macOS.

When the vm restarts the login window semi-steals focus and you can't get back into poe until you login to the windows vm (using touchid to login).... but at least at the moment parallels seems to have a bit of a big in terms of focusing that window to be able to login.

.... and if you are just in the middle of a boss fight the inevitable happens before you can get back into poe. There's 6 hours of play gone.
