Intermittent crashes.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Download and unzip/untar the attached file.  It contains an XCode project.
2. Open the project in XCode and run it.  (The code involved is minimal.) 
It will request 20 ads (from my company's test AdWhirl app) and display
them in a table view.  They refresh every 15 seconds.
3. Scroll up and down.  After at most 5 minutes of this, you should get a
crash.  I haven't figured out how to speed up the process.  More ads
doesn't seem to help.

What version of the product are you using? On what operating system?

AdWhirl 2.1.3 on OS 3.1.3

Please provide any additional information below.

The stack trace points to AdMob code, but with NSZombieEnabled set, the
warning I get is about an AdWhirlAdapterAdMob instance.

I'm sure you know about NSZombieEnabled, but I just learned about setting
MallocStackLoggingNoCompact to 1 in order to track down where a zombie
object got alloc'ed.

 (Sorry if you already knew about this.)

The zombie seems to be the currAdapter field of the AdWhirlView class.  It
looks like AdWhirl 2.1.0 and higher add a call to release that piece of
memory, and this is causing problems.

Let me know if I can help in any way.

Thanks,
David

Argh, there was a typo in the attached code that caused only one ad to be 
displayed.
 Sorry if you tried this already.  I'm attaching a corrected version.

David, do you have a crash log of some kind you can share? Send it to me 
privately if
you prefer. I'm trying to reproduce this crash and have no luck so far.
