Bug ID: 51196
           Summary: ntdll:om has a timing-related failure in Wine
           Product: Wine
           Version: 6.8
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ntdll
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

ntdll:om randomly fails with an error of the form:

om.c:2307: Test failed: got 88
and/or
om.c:2322: Test failed: got 87

The value is the time spent in RtlWaitOnAddress(..., timeout=100 ms). The test
generously expects at least 90 ms and the failure occurs whenever it is below
that.

Because the failure is intermittent and the duration typically varies between
85 and 89 ms, this failure is prone to generating false positives in the
TestBot.

Furthermore this only happens in Wine which suggests there is some
implementation issue there.

--- Comment #1 from François Gouget  ---
This is fixed:

commit e72c71d27d67462480026edc2b756a66578db7bd

ntdll/tests: Improve the RtlWaitOnAddress() timeout checks.

GetTickCount()'s granularity represents 15% of the time we want to
    mesure, making it hard to not get failures. So use NtQuerySystemTime()
    instead since we already depend on it.
    Narrow down the acceptable range again.
