New submission from Brian Kearns <[email protected]>:
between pypy default checkinterval of 10000 * 100 = 1M and the jit adapted tick
counter that can decrease to 1, threads can end up not releasing the gil for a
long time. this script takes forever to run/start additional threads on pypy on
linux64. on osx, behavior seems different and more like cpython, for whatever
reason (maybe another bug?)
import os
import thread
import sys
def f():
while 1:
os.getlogin()
for i in range(5):
print i
thread.start_new_thread(f, ())
print 'done'
