At first look this seems to be due to the tail-call-handling.
A tail-call is deferred until after we've popped the current method's 
stack frame.  Unfortunately, by that time we've also exited the 
try/catch block.

I tried some experiments to see if I could find a simple work-around.  I 
haven't so far, so perhaps I'm missing the real problem.  I'll look into 
it, but it may take a few days.  (I have to write slides for my Lisp 
conference talk, plus fix another high-priority bug for Merced.)
