We should include these fixes to improve the shell behavior under heavy background IO load:
shell/app-system: Monitor for icon theme changes
shell-global: Make saving of persistent state
global: force fsync() to worker thread when saving state
environment: reduce calls to g_time_zone_new_local()
app-cache: add ShellAppCache for GAppInfo caching
