Several people have commented to this effect, but it is normally not true
that this sequence would block, at least not for long.  Rather, "true" would
execute and exit, and "anycommand" would then receive the broken pipe
signal.  Usually this would cause it to terminate.  The net result, however,
is that, although the sequence might appear to work, "anycommand" would
terminate abnormally and could not be guaranteed to do any side effects
which it might be expected to have done, say, after processing all of
its data.
