A try/catch block usually has zero performance impact until and 
unless you actually throw an exception. The only cost is the 
tables of EIP-to-unwind information, which sit on disk until they 
get paged in by being referenced by throwing an exception.

Yes, actually throwing is very expensive. Don't do it often!
