Main issue: #15384

Text search now runs in multiple processes. Please verify that...

• There are no missing or duplicated results
• It does not look slower than before
• All the bells and whistles on the search viewlet work as before. Regex search, search/replace, etc.
• Since the search workers time out after one minute and will be restarted for the next search, test that
  • You can do a search, wait a full minute, then do another search
  • You can do two searches back to back
• Search can be canceled using esc
