adding a more or less clever microsleep and auto-retry: one problem is, the context manager isn't an asynch context manager, and hence any "microsleep" will need to run synchronously. we should be good with a micro (=very short) sleep though, and hence forcing sync should not bother the app much ..

I'll leave this issue open for now .. as an anchor until we have more feedback in using the new code
