| etc.  My problem is here:

|    def work(self):
|         print 'beginning work'
|         command = './cli.py'
|         print 'beginning os.popen'
|         file = os.popen(command, 'r')
|         print file
|         for f in file.readlines():
|             s = string.strip(f)
|             print 'put in queue: %s' % s
|             self.q.put(f, 1)
|
| Basically, the for loop here does not start processing until it has
| all of the output from the command (i.e., the pipe is closed).  Is
| there any way to read items from the pipe as they are being added (i.e.,
| while the pipe is still open)?  I have some control over the output of the
| CLI, if that helps.  Thanks.

To start with, replace readlines() with readline(), like
   while 1:
       f = file.readline()
       if not f:
           break

If that doesn't do it, then you will have to modify the program on the
other end to get it to flush its output every line.
