Manually run test_builtin on code checked out this morning:

[ 19:49 ] - ./python ../python/dist/src/Lib/test/test_builtin.py
4. Built-in functions
test_b1
__import__
abs
apply
callable
chr
cmp
coerce
compile
complex
delattr
dir
divmod
eval
execfile
filter
float
getattr
hasattr
hash
hex
id
int
isinstance
issubclass
len
list
zsh: killed     ./python ../python/dist/src/Lib/test/test_builtin.py

... so yes, it does point in that direction. The kill is manual, so
it's not likely that it made it into the long test without managing to
output to console. It did baloon in size too: it was ~140 Mbytes when
killed.
