This is a collection ticket for the hopefully soon to be held Polling Loop SIG meeting. - Please link here all issues that are believed to be related to the Device Server polling loop. - Please add an action item to the list here if you think that it would not be practical to create an issue. - [ ] Create a draft for the pluggable polling loop API (header file with doc strings) - [ ] Create documentation - [ ] Make before Tango-9 and after Tango-9 implementations pluggable - [ ] Make after Tango-9 implementation default for backwards compatibility - [ ] Reference implementation with a new polling loop #1554 - [ ] Mocked polling loop implementation for testing #1555 - [ ] Structure the polling loop implementations so that they can be unit tested independently of Tango. Ideally, the unit test can feed in a series of timestamps and verify the behaviour of the scheduler in this scenario. - [ ] **New item here!**
