re-entrancy question

[Tim Golden]

| I have a program that instantiates some objects and runs a main loop. 
| Before the main loop starts, I create a thread that listens to TCP 
| connections on a port.  If any connections are made, and depending on 
| the data, I call methods on some of those objects.
| 
| I am worried that calling methods on objects from outside the 
| main loop, 
| but that are also operated on in the main loop, could cause problems.
| 
| My questions:
| 1) is this safe?
| 2) what kind of problems could occur?
| 3) how do I safely handle this?

No doubt there are more pertinent answers, but unless this is
a learning exercise, you'd be better off investigating Pyro:

(And, thinking about it, even if this is a learning exercise)
