#4639: bad memory leak with exponentiation
------------------------------+---------------------------------------------

Comment (by robertwb):
This is a Cython error, not a coercion error. When something is returned
from within a try block, it appears the (cached) exception is not
released.
{{{
%cython
def foo():
try:
return None
except:
pass
}}}
{{{
%python
def test():
print get_memory_usage()
for i in range(100000):
try:
foo()
raise TypeError
except TypeError:
pass
print get_memory_usage()
}}}
Now {{{test()}}} will leak.
