-// to store/retrieve SignedCertificateTimestamp objects.  When stored,
-// SignedCertificateTimestamp objects are associated with a RenderProcessHost.
-// If all the RenderProcessHosts associated with the SCT have exited, the SCT
-// is removed from the store.  This class is used by the SSLManager to keep
-// track of the SCTs associated with loaded resources.  It can be accessed from

-// overflow if we register more than 2^32 - 1 SCTs in 1 browsing session (which
-// is highly unlikely to happen).
