Comment (by dd32):

 For Single-Theme/Plugin update processes, the process is:
 * Request
 * Filesystem Connect
 * Download
 * Extract ZIP
 * Enable Maintenance Mode if Multisite OR plugin/theme is in use
 * Update Plugin/Theme
 * Disable Maintenance mode

 When the Bulk Upgrader is used however, the process is a bit different,
 this includes when only one theme or plugin is chosen for upgrade:
 For Multisite bulk upgrade:
 * Request
 * Enable Maintenance Mode (with a TODO note saying that it should really
 only be enabled for an individual site rather than globally)
 * Filesystem Connect
 * For each item:
  * Download
  * Extract ZIP
  * Update Plugin/Theme
 * Disable Maintenance mode

 For single site bulk upgrade:
 * Request
 * Enable Maintenance Mode if any of the plugins/themes are in use
 * Filesystem Connect
 * For each item:
  * Download
  * Extract ZIP
  * Update Plugin/Theme
 * Disable Maintenance mode

 The Extracting of the ZIP and Updating the plugin/theme is the expensive
 part of the update process normally.
