That '-i' lies in the argv of python process not in argv of dashi.py

Here you're (this solution is /proc filesystem dependent):
---
import os, sys

try:
   path = "/proc/%d/cmdline" % (os.getpid())
   r = open(path, "r")
   cmdline = r.read()
   r.close()

   if '-i' in cmdline: #!!! i assume you're using 2.3alpha1 ;]
      print "-i is there"
   else:
      print "there's no -i"
except:
   print sys.exc_info()[1]
   sys.exit()
---

% python py.py
there's no -i
% python -i py.py
-i is there
>>>
% _

HTH.
