Reducing call stack usage for future object completions

A method, comprising:

• determining, by a processor device in a current thread, that a first future object representing a result of a first asynchronous operation has a status of complete;
• determining that the current thread is not associated with a completion queue;
• and
• responsive to determining that the current thread is not associated with a completion queue:
• creating a completion queue associated with the current thread;
• performing a completion operation of the first future object;
• determining, by the processor device in the current thread as a result of performing the completion operation of the first future object, that a second future object representing a result of a second asynchronous operation has a status of complete;
• determining that the current thread is associated with the completion queue;
• and
• responsive to determining that the current thread is associated with the completion queue, enqueuing a completion operation of the second future object in the completion queue.

A non-transitory computer-readable medium having stored thereon computer-executable instructions that, when executed, cause one or more processor devices to:

• determine, in a current thread, that a first future object representing a result of a first asynchronous operation has a status of complete;
• determine that the current thread is not associated with a completion queue;
• and
• responsive to determining that the current thread is not associated with a completion queue:
• create a completion queue associated with the current thread;
• perform a completion operation of the first future object;
• determine, in the current thread as a result of performing the completion operation of the first future object, that a second future object representing a result of a second asynchronous operation has a status of complete;
• determine that the current thread is associated with the completion queue;
• and
• responsive to determining that the current thread is associated with the completion queue, enqueue a completion operation of the second future object in the completion queue.
