I've some ideas how this could be improved:
- the exceptaddr record is stored on the stack
- the buf as well
=> saves two new and two dispose calls
- exceptaddr is a threadvar => the thread specific address
could be retrieved at procedure entry and stored
on the stack as local var as well
Much better would be a C++ like exception handling implementation
with tables but this would require a lot of work.
