Exactly. unittest block assertions are treated somewhat specially. They're 
always around with -unittest, but all the others (aside from the ones which 
can statically be determined to be false - e.g. assert(0)) get compiled out in 
-released. So, if you're relying on an assertion to go off outside of a -
unittes block in -release, you're in big trouble.
