Just a little bit of a follow up on this...
If you use win32api.TerminateProcess() instead of sys.exit(), everything
works as it should on Windows. That is, there is no longer a need to hit
'enter' one last time in order to get "inputLoop" to terminate.
So, modifying the sample code I posted earlier, the new Win32 specific
code would be the following:
import thread
import time
import sys
import win32api
def inputLoop():
while 1:
input_string = raw_input("Type something: ")
print "You entered: ", input_string
thread.start_new_thread(inputLoop, () )
time.sleep(3)
print "\nTime's up exiting...."
win32api.TerminateProcess(-1, 0)
