2020-05-04Fix flaky monotonic time.Adin Scannell
This change ensures that even platforms with some TSC issues (e.g. KVM), can get reliable monotonic time by applied a lower bound on each read. PiperOrigin-RevId: 309773801
2020-01-09New sync package.Ian Gudger
* Rename syncutil to sync. * Add aliases to sync types. * Replace existing usage of standard library sync package. This will make it easier to swap out synchronization primitives. For example, this will allow us to use primitives from github.com/sasha-s/go-deadlock to check for lock ordering violations. Updates #1472 PiperOrigin-RevId: 289033387

2018-10-17Check thread group CPU timers in the CPU clock ticker.Jamie Liu
This reduces the number of goroutines and runtime timers when ITIMER_VIRTUAL or ITIMER_PROF are enabled, or when RLIMIT_CPU is set. This also ensures that thread group CPU timers only advance if running tasks are observed at the time the CPU clock advances, mostly eliminating the possibility that a CPU timer expiration observes no running tasks and falls back to the group leader.
