Actually, this is shell-dependent. The version of ksh that I'm using, I know,
will try to create/truncate the output file before the script is even
exec()'d. Be very careful of trying this. I guess since the shell in this
case is perl, you might be ok, but in the more general sense, constructs
like this are very dangerous.
