  update
  "Updates the local map for SqueakMap, upgrading SqueakMap to the latest version if necessary.
 
  When SqueakMap is old and needs to be upgraded, it does four things that mostly make sense in the interactive world SM was built for, but are totally evil here in the world of automatic scripting:
  1. It asks the user if she wants to upgrade, in the form of a pop-up (see SMSqueakMap >> #checkVersion:).
  2. It terminates its own process.
  3. It creates a new UI process.
  (see the last line of the SqueakMap upgrade file-in: ''Project spawnNewProcessAndTerminateOld: true'', from
  http://map.squeak.org/accountbyid/9bdedc18-1525-44a6-9b79-db5d4a87f6f8/files/SqueakMap8.st
  4. It opens a SqueakMap window
 
  We work around these three problems seperately:
  1. We use #answer:with: and #withAnswersDo: to automatically answer ''Yes'' when asked if we want to upgrade
  2. We don't want this process to be terminated, so we run the update in a forked process and wait for it to finish, using #fork, #ensure:, and a Semaphore
  3. We keep track of the UI process before updating, and if it changes, we terminate the new UI process and reinstall the old one using Project >> #resumeProcess:
  4. We don't bother with the newly opened window. The other three problems are much worse.
 
  We do all this in a new process, since it is not unlikely that this method is executing in the UI process"
