Hi,

thanks to my colleague Michael Bauer I was able to identify the following issue:

Version: 2.7-slp

If I define the following callable class

class C(object): pass
C.__call__ = some_function

and execute c=C(); c() in a tasklet then some_function runs at nesting level 1.

If I change the definition of class C to

class C(object):
    __call__ = some_function

the nesting level does not increase.

The attached test script demonstrates this problem.
I would like to fix this issue for v2.7.4-slp.
