One or more techniques and/or systems are provided for managing one or more worker threads. For example, a utility list queue may be populated with a set of work item entries for execution. A set of worker threads may be initialized to execute work item entries within the utility list queue. In an example, a worker thread may be instructed to operate in a decentralized manner, such as without guidance from a timer manager thread. The worker thread may be instructed to execute work item entries that are not assigned to other worker threads and that are expired (e.g., ready for execution). The worker thread may transition into a sleep state if the utility list queue does not comprise at least one work item entry that is unassigned and expired.

Decentralized processing of worker threads

A first request to execute a first task is received from a first module in a first address space and by a second module in a second address space. The first task is placed into a task queue for execution in the second address space. Pending responses not yet returned to the first module that are results of execution for other tasks in the second address space are extracted by the second module from a response queue. Requests for the other tasks were previously sent by the first module to the second module for execution in the second address space. The pending responses are compounded. The pending responses and a return value for acknowledgement the first request to execute the first task are combined, by the second module into a combined communication. The combined communication is transmitted by the second module to the first module in the first address space.
