That's the hope.  I'm not sure WARNs get logged in Android's reporting
system.  I need to work the Android folks to figure this out.  Worst
case I may have to turn the WARN into a BUG for them (although it may
be tough to convince them to make such a change).  I'm hoping though
that the debugging information from Martin's machines will also come
through with some useful information that will allow us to root cause
whatever is causing this to happen.
