Here's the original post, quoted in its entirety: <quote> 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? </quote> Now *where* is there any mention of Twisted, either in the original post or in my reply? As I read it, the OP is doing something which creates local objects (instances, whatever) and has them available remotely. He's then -- justifiably -- concerned about possible re-entrancy if more than one outside agent makes a connection on his TCP port. It seemed to me that this was -- approximately -- what Pyro does: you created objects locally and listen on a TCP port for incoming requests. Since Pyro's author has already solved a number of the problems associated with doing this kind of thing, I thought it might be helpful to point this out.
