After commit 2f93b89b62d1 it's now:

$ toybox timeout .1 ./yes | ./count -l >/dev/null
249135104 bytes, 238Mb, 2.3Gb/s, 0m00s
$ toybox timeout .2 ./yes | ./count -l >/dev/null
512294912 bytes, 489Mb, 2.3Gb/s, 0m00s
$ toybox timeout .6 ./yes | ./count -l >/dev/null
1665302528 bytes, 1.5Gb, 2.5Gb/s, 0m00s
$ toybox timeout 1 ./yes | ./count -l >/dev/null
2610102272 bytes, 2.4Gb, 2.4Gb/s, 0m01s

I had to explicitly use toybox timeout because debian's timeout doesn't seem to
actually call the child process for .2 seconds or less. No, I don't have a clear
idea how to add this to the test suite yet, but I'm calling it good enough for now.
