/*

* Since the consumer thread can be spawned at any moment in time, we init

* the health to a poll status (1, which is a valid health over time).

* When the thread starts, we update here the health to a "code" path being

* an even value so this thread, when reaching a poll wait, does not

* trigger an error with an even value.

*

* Here is the use case we avoid.

*

* +1: the first poll update during initialization (main())

* +2 * x: multiple code update once in this thread.

* +1: poll wait in this thread (being a good health state).

* == even number which after the wait period shows as a bad health.

*

* In a nutshell, the following poll update to the health state brings back

* the state to an even value meaning a code path.
