I'm not entirely sure what you're trying to achieve,
or what "reuse the running process" means. This WMI
snippet will tell you whether a given pid is running
or not. As you may know, WMI isn't the fastest thing
on earth, but it may be fast enough for you.

<code>
import wmi

pid = int (raw_input ("Enter PID:"))

c = wmi.WMI (find_classes=False)
for process in c.Win32_Process ([], ProcessId=pid):
   print "PID %s in use by %s" % (pid, process.Caption)
   break
else:
   print "PID %d not in use" % pid

</code>
