import sys, os, time
texts = ['this is text1', 'this is text2']
for current_text in env_sources[0:]:
pid = os.fork()
if pid == 0:
time.sleep(2)
print current_text
break
if pid != 0:
os.waitpid(-1, 0)
print 'this is the end'
Basically, make sure that none of the children run the waitpid and
last print.
