If you are in control of both processes, you could use a pidfile and
check if it's there and has a pid in it and if that pid is running.
If it's not there, start the task.  If it's there, but the pid isn't
running, remove the pidfile.  You could also use a semaphore or mutex.

If you don't have control of the other process, look at Win32::GUI/GuiTest
to use for finding an active process and maybe Win32::Process to create
a new own and control it.
