- The 'threaded' build has multiple Tasks, but a single Capability.
- At any one time only one task executing STG code, other tasks are
- either busy executing code outside the RTS (e.g., a C call) or
- waiting for their turn to (again) evaluate some STG code. A task
- relinquishes its RTS token when it is asked to evaluate an external
+ The THREADED_RTS build allows multiple tasks and mulitple Capabilities.
+ Multiple Tasks may all be running Haskell code simultaneously. A task
