/**
* Indicates whether all mind threads have been JOLTed at least once.
*
* JOLTing serves two critical purposes:
*
* 1. **Global Constructor Sequencing**: Since pthreads begin executing while
* global constructors are still being executed, globally defined pthreads
* cannot depend on global objects having been constructed. JOLTing is done
* by the CRT's main thread within main(), which provides a sequencing
* guarantee that global constructors have been called.
*
* 2. **shared_from_this Safety**: shared_from_this() requires a prior
* shared_ptr handle to be established. The global list of
* shared_ptr<ComponentThread> guarantees that at least one shared_ptr to
* each ComponentThread has been initialized before JOLTing occurs.
*
* This flag ensures that JOLTing happens exactly once and provides
* a synchronization point for the entire system initialization.
