## Motivation Similar to #1666, it is no longer necessary to lazily register delays with the executions default timer. All delays are expected to be created from within a runtime, and should panic if not done so. ## Solution `tokio::time` now assumes there to be a `CURRENT_TIMER` set when creating a delay; this can be assumed if called within a tokio runtime. If there is no current timer, the application will panic with a "no current timer" message. ## Follow-up Similar to #1666, `HandlePriv` can probably be removed, but this mainly prepares for 0.2 API changes. Because it is not in the public API, this can be done in a following change. Signed-off-by: Kevin Leimkuhler <kleimkuhler@icloud.com>
