Hi Heres a poser. I want to start a program 4 times at exactly the same time (emulating 4 separate users starting up the same program). I am using pexpect to run the program from 4 separate locations accross the network. How do I start the programs running at exactly the same time? I want to time how long it takes each program to complete and to show if any of the program initiations failed. I also want to check for race conditions. The program that I am running is immaterial for this question - it could be mysql running queries on the same database for example. Using threading, you call start() to start each thread but if I call start on each instance in turn I am not starting simultaneously. A
