I agree.

Knowing where to put the printf is quite difficult for IKVM, but I just
started Eclipse 3.0M8 and looked at the .NET performance counter for the
number of exceptions and it was about 21000.
This number is an upper limit, because of the way the two systems differ
in exception handling some (most?) exceptions are counted multiple times
as they percolate up the stack.
