Yeah that's what I was thinking when I wrote it.  Python can't know how
czmq was compiled with ZSOCK_NOCHECK unless I expose it and that sounded
ugly to me, so instead I have:

@cdef('zsock_t * zsock_new_ (int type, const char *filename, size_t
def new(type, filename=None, line_nbr=None):
    if filename is None:
        frame = inspect.stack()[1][0]
        info = inspect.getframeinfo(frame)
        filename = info.filename
        line_nbr = info.lineno
    return ffi.gc(C.zsock_new_(type, filename, line_nbr), destroy)

Which sidesteps the issue by calling zsock_new_ directly with file and line
information from the frame's caller.  I don't think __FILE__ and __LINE__
would be useful to a pyczmq user, as it would end up referencing a
generated C file internal to CFFI.
