If this is true, sorry, I didn't had the impression.

I also think that in an earlier mail I answered, that errors can leave you 
with corrupt data, say invalid file handles, memory pointers, or data 
structures that violate invariants. You won't like to close files from 
invalid file handles and free memory from corrupt pointers or run into 
infinite loops by traversing the corrupt data structures. That's the 
reason why it is better to stop execution of the program and hand over 
control to the next higher level, say the shell or the web browser, that 
can free resources safely.
