need help checking for stack overflow in Win32

[Guido van Rossum]

I could use some help from someone with a little time, some knowledge
of Python internals, and some Win32 C expertise.  On Win32 platforms,
infinite recursion causes an Application Error (a fatal windows
error).  There is some machinery in Python to check for this
condition, but apparently it doesn't work on Win32.  Please help!
