The context value you pass into record isn't used and running record in its
own goroutine doesn't really add anything because the main goroutine just
waits for the other goroutine to exit. The exit the second goroutine will
be at least 1 second, but could be much longer.

Thanks for all the comments. I did finally figure it
out. https://play.golang.org/p/ghCT6DCDLJz
On lines 69-70 changed that code from and exec.Command to exec.Start
allowing me to sleep for the desired amount of time and then signal(sigint)
the command via cmd.Process.Signal(syscall.SIGINT)

Hmm... *Do not communicate by sharing memory; instead, share memor
Juct use the same context to your ExecContexts and cancel it on success to make
the other stop.

Okay, I realize now that I didn't do a very good job in my first post of
explaining my problem, so I'll trying again. In the above code I need to
signal(sigint or sigterm) the exec.CommandContext on line 69 that is
blocking so it will stop and finish the g
Thanks for the info. I will look at the context information.
