Yes, that introduces some fuzz, but I think the principle remains
viable -- the kernel will only buffer so much.

Consider the following using a timeout.c modified with the attached
patch, and a small Perl program (below) than hangs after 10 seconds:

$ time yes | src/timeout -i 2s ./write_then_hang 10 >/dev/null

real    0m11.777s
user    0m0.656s
sys     0m0.068s

#!/usr/bin/perl -w

my $n = shift @ARGV || 10;

my $s = time;

print scalar(<STDIN>) while (time - $s < $n);

while(1){ }
