Bug #: 30807
           Summary: Thread IDs are &~3 (multiples of 4) on Windows.
                    Application presumes this behavior and fails
           Product: Wine
           Version: unspecified
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: kernel32
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

On Win7-64(and i suspect -32 on NT,2k,XP,Vista) the Thread ID's are all
multiples of 4.  This "feature" is used within an application.  Wine currently
produces thread ID values multiples of 1.  Here is some Microsoft Insider
chatter about it:

I would like to see Wine changed to only issue Thread ID values as multiples of
4, in line with how Windows works.  Granted there are no official reasons why
thread IDs should be multiples of 4, but given this has been the behavior of
the NT kernel from as far back as, well, NT! it seems like something that
should be done for maximum compatibility.  Without this, applications that have
presumed this multiple will have very subtle bugs, something not easily
detected.

Actually the bugs should be fairly obvious. What application actually depends
on this?

Boris: Which apps fail because of this?
