It's not a magic bullet to prevent goroutine leaks... I guess the
advantage of setting the size to 1 means that the writing goroutine will
be able to write and exit, even if you forget to read the channel
elsewhere.

If your code falls over with a buffer size of 10, it'll probably fall
over (but slower) with a buffer size of 1000 -- that, or it'll
"complete" but still be wrong.
