[issue3373] sys recursion limit a lot shorter on trunk?

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

Why was 1000 chosen in the first place? If it's just an arbitrary value
then we can bump it to 4000 so that people don't get bad surprises when
upgrading their Python.

Well PyObject_Call increases the recursion count, and entering __init__
will increase it once more. That explains the 2x, not the 4x though.
