- Wait/Test Clarifications
- Discussed previously proposed changes for definition of "atomic compatible" and wait/test; see #204
- Jim read the changes proposed in #267
- Reviewed proposed atomicity of wait/test, with consideration for compatibility with proposed signal operations (see #244, put-with-signal)
- Discussed "not valid" vs. "not necessarily valid" with respect to
shmem_ptr, and concerns about restricting implementations with "not valid" requirements; favors undefined behavior. - Discussed performance concerns about atomicity requirements for wait/test leading to additional network atomics.
- Discussed implicit undefined behavior (i.e., the Specification does not address this behavior) vs.
- Discussed how #267 clarifies the existing memory model (where it was previously undefined) vs. adding new interfaces, such as opaque counter objects.
