Looks like it's built with the value of PIPE_BUF from
include/linux/limits.h

Through a binary search, on my system (16K pages) with the original
test program, setting pipe_buf to 10923 fails with EAGAIN, but add one
more byte (10924) and it works.  I can't immediately see how that
number relates to anything.
