still, user programs like bash could have a race problem by spliting the input, I hope that they can somehow take care of this problem themselves.
stdio is *not* always your friend. fopen/fprintf is prone to splitting on bugger boundaries without your knowing about it, but most language bindings (including the Perl you tested with) allow you to use open/write and do the buffer management yourself
Actually, the Perl's IO layer did pretty little to the result, because Anh used command line substitution: echo $(perl -e "print 'a'x2000") > /dev/sample Jonathan
