Robert,

Thanks for your answer.

I've tried your modified version.  Here is a typical output when
attempting once to write in the closed pipe :
----------------------------------------------
(Unexpectedly) passed 960 times;
{Errno::EPIPE=>38, Errno::ECONNRESET=>2}
----------------------------------------------

... this to be compared with typical output when attempting to write
6th times in a row in the closed pipe :
----------------------------------------------
(Unexpectedly) passed 4 times;
{Errno::EPIPE=>987, Errno::ECONNRESET=>9}
----------------------------------------------

Strangely enough, I don't seem to get any Errno::ECONNABORTED ever.

I've reached the same conclusion -- which brings me to the question:
what can I do to make the combination of timing and buffering
predictible?  Or how may I get around it?
