I think none of them. Imagine that you access a file over the network. Now, a network error can suddenly terminate your program (you users will be very surprised) or can be missed that leads to the possible loss of data (they will be surprised also). Generally speaking, GC is not suitable for resource deallocation - this should be done synchroniously (generating and catching exceptions). > What I dislike is resource leaks- as plugging the holes manually can often > be tricky.
