Isn't it possible to do something similar to what is described here:

    http://msdn.microsoft.com/en-us/library/ms686997%28v=vs.85%29   ?

As I understand it, we only need one TLS index, which can be stored in a
global variable in a new pixman-win32.c file. That index is then used
with TlsSetValue and TlsGetValue to set and get the thread local data,
and can be released with TlsFree() when DllMain() is acalled with

Note, I don't really know the Windows API, so I might be
misunderstanding something here.
