[NGINX] cache process manager consume a lot of CPU at reload and has to be restarted

[omega8cc]

One possible reason could be some race condition when the server is
still running in the reload state and it receives another reload command
- this can be caused by provision in Aegir system for Drupal, as it
reloads nginx sometimes two times during one action, like platform/site
migration to make sure all vhosts are reloaded correctly.
