I'm still not sure what this gets you. In production code, if you're
doing extra work to only error correct one level deep, you still have
an error which will cause the program to crash with a backtrace --
arguably the same backtrace it would have crashed with had you not
limited your rescue one level deep.  If you're debugging it's more
useful, buy I think that having asserts and logging setup against
all rescues might be a better approach, just to get an idea of your code is
tripping any rescue clauses frequently.

Hmm, is there a way to hook into the rescue clauses to automatically
log all rescue events? A callback might be nice. Maybe I'll poke 
around and see if anything interesting occurs to me.
