Bug ID: 55429
           Summary: psapi:psapi_main - test_GetPerformanceInfo() sometimes
                    fails on Windows
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: psapi
          Assignee: [e-mail]
          Reporter: [e-mail]

psapi:psapi_main - test_GetPerformanceInfo() sometimes fails on Windows:

psapi_main.c:716: Test failed: expected approximately 1131 but got 1125

See https://test.winehq.org/data/patterns.html#psapi:psapi_main

There are three known instances so far:
* 2023-06-16 win1607_newtb-w1064v1607-32
* 2023-06-28 win21H1_newtb-w10pro64-pt-BR-64
* 2023-08-08 win2004_newtb-w10pro64v2004-64

The test counts the total number of threads on the machine in two different
ways and expects to find the same or a close enough result. In this case some
process with 6 threads must have stopped while the test was running, thus
causing the failure.
The test also counts handles and processes, both of which could probably also
fail in the same way.

I think this is another good candidate for the tryok() patch from MR!3418.
