Nothing, i cannot reproduce it :(
This is the code:
use strict;
use warnings;
sub streamer {
my $responder = shift;
my $writer = $responder->([200, ['Content-Type' => 'text/plain']]);
$writer->write("Oops...\n");
$writer->close();
}
my $app = sub {
my $env = shift;
return \&streamer;
};
The memory usage is super-stable:

Can you re-run the same test with $writer->write("Oops...\n"); commented ?
if commenting it solves your issue we will know where to look at, and
eventually do an ad-hoc fix
