TSAN reports data races

[alokpr]

TSAN emits whole bunch of data race warnings on a simple single publisher, single subscriber application. Log attached. Threading model of the application:

• Both publisher and subscriber are on the main thread
• Client on a dedicated thread
• Embedded driver on a dedicated thread with a shared threading strategy

Many (all?) of the warnings look like false positives due to atomic operations that TSAN does not understand. The list of supported operations are documented here: https://github.com/google/sanitizers/wiki/ThreadSanitizerAtomicOperations
