For those who like such factoids, AIX uses 0xdeadbeef similarly
for uninitialized data.  Prior to FreeBSD 2.1.0, we used 0xdeedbeef
as well, but that was changed and accompanied by this cute log 
message:

 Make vegetarian and animal rights people happy and use 0xdeadc0de instead
 of 0xdeadbeef as the fill pattern. Decreased MAX_COPY to 64 (256 was a bit
 overzealous in most cases).
