…otnet#64834) * Add support for Windows IO completions to the portable thread pool - Added an implementation for BindHandle - Polling for IO completions is done in batches on separate threads similarly to what is done on Unixes - Added a high-priority work item queue to have IO completion work items run at higher priority - Removed the time-sensitive work item queue, used the high-priority queue instead
