Discussion:
the error handling for the constructor for condition_variable
distinguishes lack of memory from lack of other resources, but the error
handling for the thread constructor does not. Is this difference
intentional?

The proposed resolution assumes 962 has been accepted and its proposed resolution applied to the working paper.

Move to Ready.
Proposed resolution:
Change Mutex requirements 33.6.4 [thread.mutex.requirements], paragraph 4, as indicated:
Error conditions:
not_enough_memory— if there is not enough memory to construct the mutex object.resource_unavailable_try_again— if any native handle type manipulated is not available.operation_not_permitted— if the thread does not have the necessary permission to change the state of the mutex object.device_or_resource_busy— if any native handle type manipulated is already locked.invalid_argument— if any native handle type manipulated as part of mutex construction is incorrect.
Change Class condition_variable 33.7.4 [thread.condition.condvar],
default constructor, as indicated:
condition_variable();Effects: Constructs an object of type
condition_variable.Throws:
std::system_errorwhen an exception is required (33.2.2 [thread.req.exception]).Error conditions:
not_enough_memory— if a memory limitation prevents initialization.resource_unavailable_try_again— if some non-memory resource limitation prevents initialization.device_or_resource_busy— if attempting to initialize a previously-initialized but as of yet undestroyedcondition_variable.
