void RegisterUniqueRangeDeleter	(	UniqueRangeDeleter	deleter,
		volatile IdxDeleter *	idxDeleter
	)

register a deleter, returning its index within the table.

Parameters

deleter	function pointer. must be uniquely associated with the idxDeleter storage location.
idxDeleter	location where to store the next available index. if it is already non-zero, skip the call to this function to avoid overhead.

thread-safe. idxDeleter is used for mutual exclusion between multiple callers for the same deleter. concurrent registration of different deleters is also safe due to atomic increments.

halts the program if more than allocationAlignment deleters are to be registered.
