I tried to test this with threads using the following program and it
doesn't seem to respond to interrupts.
import threading
import numpy.core.multiarray as ncm
class mythread(threading.Thread):
def run(self):
print "Starting thread", self.getName()
ncm.test_interrupt(1)
print "Ending thread", self.getName()
m1 = mythread()
m2 = mythread()
m1.start()
m2.start()
