Certificate management functions where added to dart:io in r25610 and r26002. However these functions where mutating the NSS database for the whole Dart process, and some functions where also persisting the changes to the database. This might cause issues when running multiple isolates as changes in one isolate will affect other isolates and could lead to unexpected results. These functions are removed from dart:io for now.
