IronPython在线程中使用numpy时会抛出InsufficientMemoryException

我有一些从C#应用程序中调用的IronPython代码。
这段代码工作得很好，直到我决定改变一个函数在线程中运行。
当在python线程中调用numpy函数时，会抛出InsufficientMemoryException异常。
我寻找解决办法，但没有找到。有人能解释一下为什么会发生这种情况，我该如何解决它?

我认为这只发生当我有两个线程使用numpy

我这样运行代码:

c#

:

_python.functionA(); # _python was created with "Python.CreateEngine()"
_python.functionA(); # twice on purpose

Python:

my_python_script.py

import threading
import time
import numpy
def blah():    
    print numpy.array([100,100,0])
def functionA():
    t = threading.Timer(0,blah)    
    t.start()
    time.sleep(2)

And I got this Exception:

Exception in thread Thread-1:
Traceback (most recent call last):
  File "c:'Program Files'IronPython 2.7.1'Lib'threading.py", line 552, in _Thread__bootstrap_inner
    self.run()
  File "c:'Program Files'IronPython 2.7.1'Lib'threading.py", line 756, in run
    self.function(*self.args, **self.kwargs)
  File "C:'workspace'my_python_script.py", line 113, in blah
    print numpy.array([100,100,0])
MemoryError: Exception of type 'System.InsufficientMemoryException' was thrown.

我得到这个异常，即使我只运行一个线程，通过IronPython解释器，没有c#:
