-// 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) |
