BTW, from what I understand, the $| variable does not guarantee that the OS
will actually perform an instantaenous write.
Can someone comment on this?

Yes, IO:Tee is an alternative; here's sample code that uses it.

#______________________code starts_____________________
use IO::Tee;
#Multiplex output to multiple output handles

my $tee = IO::Tee->new ( ">$first_file", ">$second_file");
#Bind $tee to $first_file and $second_file
#Notice that file handles are not used.

$| = 1;

print $tee "\nMail comments about $0 to

#Flush the output buffer
#______________________code ends_____________________
