This uses a GCC compile time option to inject race detectors into the code.
The code as a result runs a lot slower. Since, there is no code that I have
written as part of this, I don't see how it would be possible to add this
to the production executable.

However, it should be possible to debug an issue by replicating the same
environment and running the race-detection compiled code. This should work
since the flags used detect potential race conditions, and hence should
detect if there will exist any races in that run. Else, the problem
probably lies somewhere else.

Thanking You,
