| |
| Thread local storage for a set of flags that are updated based the continuation |
| currently running in the thread. These flags are handy if the data is needed |
| as a "global" in parts of the code where the original net VC is not available. |
| Storing the flags in the void * of the thread key directly. I assume we are on |
| at least a 32 bit architecture, so the rawflags size is 32 bits. |
