yup.
Perl checks it to see whether or not to "auto"-flush when you send
output. You can also set it on filehandles you open by select()'ing
them first:
{ open FH, ">$whatever" or die $!;
my $prevh = select FH; $|=1; select $prevh;
} # now FH will autoflush =o)
The $prevh bit is just if you want to be sure to reset the default
filehandle, such as when you're in a function and don't know for sure
that it's still STDOUT. I only added the braces to scope the my()....
