[issue815646] thread unsafe file objects cause crash

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

A small addition to Christian's code snippet allows me to reproduce the
problem as well:

import thread

f=open("tmp1", "w")

def worker():
    global f
    while 1:
        f.close()
        f = open("tmp1", "w")
        f.seek(0,0) 

thread.start_new_thread(worker, ())
thread.start_new_thread(worker, ())

while 1:
    pass
