Bug ID: 54094
           Summary: kernel32:process - test_services_exe() sometimes fails
                    due to an invalid buffer size in Windows
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: kernel32
          Assignee: [e-mail]
          Reporter: [e-mail]

test_services_exe() sometimes fails due to an invalid buffer size in Windows:

process.c:4962: Test failed: got 0xc0000004

See https://test.winehq.org/data/patterns.html#kernel32:process

Where 0xc0000004 == STATUS_INFO_LENGTH_MISMATCH

This causes a little bit over one failure per month.

I think the failure simply happens when a process is started between the first
call to NtQuerySystemInformation(), which returns the buffer size to hold the
*array* of SYSTEM_PROCESS_INFORMATION structures, and the time we call it again
with that size. Obviously we don't start new processes ourselves so it must be
a scheduled task or some equivalent.

We should probably loop a couple of times to defend against that.
