tombstones created when i exit droidwall

```
What steps will reproduce the problem?
I could't reproduce it always with the same steps.

What is the expected output?
Just exit.
What do you see instead?
Droidwall exits, no FC, i just remarked the tombstones created at the exact
time i exit.

What version of the product are you using? On what operating system?
v.1.5.7 on android 2.3.3 lg p500

Please provide any additional information below.
Sometimes when i exit droid wall a tombstone is created(i'm sure all the
tombstones are created only when i press exit, looking at the time the
tombstones were created). I couldn't find the steps to reproduce this, i tried
almost all the variants (start app from block list-open droid-kill blocked
app-open droid wall-exit droid wall, start more apps-open droid wall- exit
droid wall etc..) it happens somehow aleatory, i think it has something to do
with opening an app from block list and then open-close droid wall.

tombstone:

Review the attached tombstone logs and the reported exit sequences, including opening an app from the block list before closing DroidWall. Reproduce the issue on Android 2.3.3 if possible, then verify that exiting DroidWall no longer creates a tombstone.
