liuzhenhai:

it seems that pypy(version 2.6) can not recognize and jit the cffi function without lib.xxxfunction calling way. Here is the code.
```
#!python
from cffi import FFI
ffi=FFI()
ffi.cdef('''
int add(int a, int b);
''')
ffi.set_source('_my_test','''
int add(int a, int b){
  return a+b;
}
''')
ffi.compile()

from _my_test import ffi,lib
%timeit lib.add(1,2) 
add=lib.add
%timeit add(1,2) # slower than lib.add(1,2) about 6x

```
