-// ----------------- |
-// Threading: |
-// ----------------- |
-// |
-// Unless otherwise noted, functions in webcrypto::platform are called |
-// exclusively from a sequenced worker pool. |
-// |
-// This means that operations using a given key cannot occur in |
-// parallel and it is not necessary to guard against concurrent usage. |
-// |
-// The exceptions are: |
-// |
-// * Key::ThreadSafeSerializeForClone(), which is called from the |
-// target Blink thread during structured clone. |
-// |
-// * ImportKeyRaw(), ImportKeySpki(), ImportKeyPkcs8(), which can be |
-// called from the target Blink thread during structured clone |
-// deserialization, as well as from the webcrypto worker pool. |
-// |
-// TODO(eroman): Change it so import happens in worker pool too. |
