  Lots of bugs are not caught by Windows 95 because it does not allow zero
page protection !

  Why don't we simply fill this page with NOP
and a call to a fake exception at the very end of it ?

  This would insure that all code reaching this area will terminate

  Of course reading data in this region will still not be caught but
reading a longint or a pointer would give 0x90909090
that has big chances to be invalid !
