On some platforms,
tokio::time::sleep
will sleep according to system uptime, not according to the wall clock. This means that for some operations that are time-sensitive, like token refreshes, tasks will sleep for too long when waking up from an OS suspend.To fix this, we introduce
sleep_systime
, which sleeps in small increments, checking wall clock time on wakeup, and otherwise marshalls out directly totokio::time::sleep
for short durations as they don't generally cause usability issues.Closes BLO-1707
