Yes; "link /dump /headers" shows the same thing.

Why isn't pythonw.exe based at 00400000 like most well-behaved executables?
Rebasing to 1E190000 unnecessarily fragments linear space.

tcl83.dll is at the default base of 10000000.  _tkinter.pyd is set to
1E190000, same as pythonw.exe.

I have to believe the pythonw.exe base address is a bug.
