The dumped 0x66 comes from a 6.6x PSP, and 5.50's shell rejects any schema
version above 0x58 as a corrupt registry - it drew its whole XMB and then
replaced it with the "settings are corrupt, press O to repair" dialog.

We hand every sceRegOpenRegistry the same handle 0, so closing one used to wipe
every open category - including ones a still-open registry handle owns. On
hardware each open gets its own object and they don't interfere.
The VSH's alarm scan does exactly this: it holds /CONFIG/ALARM open, then opens
and closes the registry once per alarm slot, and found its own category gone by
the end. Count the opens and only clear on the last close.
