Re: Parent process does not wait for Child processes to finish and exits after the waitpid statement

You're using Win32::Process so you're probably running this on Windows. I have my doubts if using a Unix mechanism on Windows is the best way to do it, or even if it'll work well.
Actually, fork on Windows doesn't start a new program. It starts a new thread.
Next, you're calling exec in the child ~~process~~ thread. exec doesn't return.
What does running an LWP request have to do with anything? OK, I'm officially confused now.

In short: if this is Windows, I think your program is killed by exec in the child.

Thanks for the comments... I did not realize that fork() may have issues on the windows platform. I would try spawning a thread for each process and then have the parent wait for those threads to exit. Would also need to capture the exit status of the parent if exiting abruptly. Thanks again..
