New issue 2017: greenlet.switch() raises MemoryError
https://bitbucket.org/pypy/pypy/issue/2017/greenletswitch-raises-memoryerror
nxsofsys:
Follwing script runned on [PyPy 2.5.1 with MSC v.1500 32 bit] (WIndows 7 x64)
```
#!python
import greenlet
from time import time
N = 1000 * 1000
count = 0
def func():
global count
count += 1
main.switch()
main = greenlet.getcurrent()
try:
start = time()
for i in xrange(N):
greenlet.greenlet(func).switch()
except:
raise
finally:
print '%s switches took %.3fs' % (count, time() - start)
```
prints following output:
```
2793 switches took 0.217s
Traceback (most recent call last):
File "<builtin>/app_main.py", line 75, in run_toplevel
File "bench.py", line 15, in <module>
greenlet.greenlet(func).switch()
File "C:\Env\pypy\lib_pypy\greenlet.py", line 53, in switch
return self.__switch('switch', (args, kwds))
File "C:\Env\pypy\lib_pypy\greenlet.py", line 69, in __switch
_continulet.__init__(target, greenlet_func, *baseargs)
MemoryError
```
but on CPython with greenlet runs without errors.
