   // We used to remember the intermediate CA certs in the NSS database
   // persistently.  However, NSS opens a connection to the SQLite database
   // during NSS initialization and doesn't close the connection until NSS
   // shuts down.  If the file system where the database resides is gone,
   // the database connection goes bad.  What's worse, the connection won't
   // recover when the file system comes back.  Until this NSS or SQLite bug
   // is fixed, we need to  avoid using the NSS database for non-essential
   // purposes.  See https://bugzilla.mozilla.org/show_bug.cgi?id=508081 and
   // http://crbug.com/15630 for more info.
