Comment(by vbraun):
I tried the following in `cdef class Action`:
{{{
#!python
def __cinit__(self):
print 'Action __cinit__ ' + str(id(self))
def __dealloc__(self):
print 'Action __dealloc__ ' + str(id(self))
}}}
then I do get occasionally reused id (=memory address in CPython), for
example
{{{
Action __cinit__ 105376976
Action __dealloc__ 105376976
Action __cinit__ 105376976
Action __dealloc__ 105376976
}}}
But I don't see any double finalizers without the object being constructed
in-between. I also don't get any segfault in
`bordeaux_2008/half_integral.rst`.
