myserver. If so, what is the correct way to restart the daemon? Will it
work to run the restart command in a subprocess rather than a subshell or
will a subprocess also terminate when its parent terminates?

illustrate the problem, but the test program works perfectly. I could post
it, though, if it would help to understand what I am doing -- and what
might be wrong in the real program.

I use sys.stdout.write('\a') to beep. It works fine on Kubuntu, but not on
two other platforms (one of which is Ubuntu). I presume that the problem
is due to a system configuration issue. Can someone point me in the right
direction? Thanks.

Nice. One thing: how do I get the uid and gid for the target user? In

the OS to that user could be different on different systems.

tement, so I have to carve up the
list as source. Using Pyro to send the chunks once I have them should work
fine. Note that I am avoiding the use of the term "slice". It is not
possible to slice the list in the way that we normally do in Python because
it is still in the form of a str
some number of Things delimited by "Thing(" at one end and "),\nThing("
at the other (or ")]\n" at the end of the list). Did I just answer my own
question?
Of course, I need to balance the complexity of any alternative solution
against simply executing the statemen
I'm sorry that I took the time to respond.

another program, read the nonpickle-format file and rewrite the pickle with

how to make Tkinter work under Python 2.4?
I also don't understand why I have to go to all this trouble. Tkinter
is supposed to be included with Python, so shouldn't it be available
without any special effort?
