* It is because of this implicit close() that we created the
* copy of the original.
*
* Note that the OS can recycle HANDLE (numbers) just like it
* recycles fd (numbers), so we must update the cached value
* of "console". You can use GetFileType() to see that
* handle and _get_osfhandle(fd) may have the same number
* value, but they refer to different actual files now.
* Note that we need to update the cached console handle to the
* duplicated one because the dup2() call will implicitly close
* the original one.
*
* Note that dup2() when given target := {0,1,2} will also
* call SetStdHandle(), so we don't need to worry about that.
