Currently, on every throw statement, traceHandler is invoked, which
significantly slows down exception handling.
It would be nice to invoke traceHandler only if there is no user-defined catch
specified (if there is one, stack-trace is not [or rarely] used, AFAIK).
This should improve exception handling performance drastically (more than 1000x
in my test).
