File descriptors get shared between parent and child processes...just because a child process terminates doesn't necessarily mean that you want to close everything.

Well, if POSIX 2008's O_CLOEXEC becomes more popular, folks can control whether a descriptor gets inherited an open() time, rather than needing fcntl()'s FD_CLOEXEC and deal with possible race conditions (especially multithreaded programs)...
