Currently, sysmon relaxes the Windows timer resolution as soon as the Go process becomes idle. However, if it's going idle because of a short sleep (< 15.6 ms), this can turn that short sleep into a long sleep (15.6 ms). To address this, wait for 60 ms of idleness before relaxing the timer resolution. It would be better to check the time until the next wakeup and relax immediately if it makes sense, but there's currently no interaction between sysmon and the timer subsystem, so adding this simple delay is a much simpler and safer change for late in the release cycle. Fixes #20937.
