The comment should point out that this function doesn't initialize NSS.

Please rename this function EarlySetupForNSSInit (or something along that line).

 // Initialize NRPR if it isn't already initialized.  This function is
 // thread-safe, and NSPR will only ever be initialized once.  NSPR will be
 // properly shut down on program exit.
