-/////////////////////////////////////////////////////////////////////////////
-//
-// Threading within SSLClientSocketNSS and SSLClientSocketNSS::Core:
-//
-// Because NSS may block on either hardware or user input during operations
-// such as signing, creating certificates, or locating private keys, the Core
-// handles all of the interactions with the underlying NSS SSL socket, so
-// that these blocking calls can be executed on a dedicated task runner.
-//
-// Note that the network task runner and the NSS task runner may be executing
-// on the same thread. If that happens, then it's more performant to try to
-// complete as much work as possible synchronously, even if it might block,
-// rather than continually PostTask-ing to the same thread.
-//
-// Because NSS functions should only be called on the NSS task runner, while
-// I/O resources should only be accessed on the network task runner, most
-// public functions are implemented via three methods, each with different
-// task runner affinities.
-//
-// In the single-threaded mode (where the network and NSS task runners run on
-// the same thread), these are all attempted synchronously, while in the
-// multi-threaded mode, message passing is used.
-//
-// 1) NSS Task Runner: Execute NSS function (DoPayloadRead, DoPayloadWrite,
-// DoHandshake)
-// 2) NSS Task Runner: Prepare data to go from NSS to an IO function:
-// (BufferRecv, BufferSend)
-// 3) Network Task Runner: Perform IO on that data (DoBufferRecv,
-// DoBufferSend, DoGetChannelID, OnGetChannelIDComplete)
-// 4) Both Task Runners: Callback for asynchronous completion or to marshal
-// data from the network task runner back to NSS (BufferRecvComplete,
-// BufferSendComplete, OnHandshakeIOComplete)
