OS/2 provides this...  Different memory areas can have varying levels of
protection.  When this protection is broken, whether by attempting to modify,
read, whatever (depends on the protection) the program is promptly aborted but
with appropriate error info...

Although I personally don't have or use OS/2 I obtained this information from
the OS/2 Programmer's Guide by Ed Iacobucci (The leader of the IBM OS/2
Design Team)

Sounds great to me...
