I am forking and running a separate tcl script in the background, so that I can kill it if it hangs. I need to know the exit status of the process, can I do this using the PID that it returns?

The status of the child process is encoded in $::errorCode. See

for a complete description of how to decode $::errorCode after an [exec].
