- It doesn't. Who told you that it did?
-
- The only exception to this is if you do the $WAITFR when you are already at
- AST level.... that DOES block further ASTs at the same access mode... because
- the "AST active" status is saved with your process context when you enter the
- wait state. However, higher-mode ASTs can still be delivered.
