I'm extremely confused by this statement.  Currently, some the
USER_SHARED_DATA values are written at process start, and some are not
written at all.  How can external code possibly rely on Wine's current
broken behavior?  Any code written for windows expects these values to
update every 15.6 ms.

If anything, I would expect updating these values to fix copy protection
schemes, not break them.
