0x7ffe0000 is SharedUserData that is present on all NT+ systems. It's format
only documented in DDK for kernel address space and only for some first several values.
This structure keeps growing as I understand and no one except MS knows what's
all in it. We do need this structure for some programs that use it. The trick
is, that it's in the space allocated with read only access (for user programs).
And marked as private. I think we'll have to do something like that. And update
from the server.
