I had a perl script in which I opened a file thus

open(FOO, "| filter");

and then did a bunch of writes to FOO. My script exited by just
falling through the end, and the output never got to the filter. 
Finally, I put a

close(FOO);

at the end of the script, and it worked. Should all filehandles be closed 
before exiting?
