Subject: Excessive Windows registry accesses

When I invoke GNU Emacs (24.4.1 (x86_64-w64-mingw32) of 2014-10-21 on KAEL) 
on Windows 7, it makes an enormous number of what seem (to me) unnecessary 
identical registry accesses.

20 times each:

    QueryValue: HKLM\System\CurrentControlSet\Control\Nls\CodePage\28605 
(success)
    QueryValue: HKLM\System\CurrentControlSet\Control\Nls\CodePage\28604 
(name not found)

1849 times each in quick succession (!):

    OpenKey: HKCU\SOFTWARE\GNU\Emacs (name not found)
    OpenKey: HKLM\SOFTWARE\GNU\Emacs (name not found)

1850 times likewise (also !):

    QueryKey: HKCU (success -- unsurprisingly)

and likewise finally, 1884 times:

    QueryKey: HKLM (more unsurprising success)

Why?
