Subject: puts sometimes gives:in `write': Interrupted system call (Errno::EINTR)

I sometimes get the error message:
./parallel.rb:465:in `write': Interrupted system call (Errno::EINTR)
which is actually from a line

465             puts "deassign: job is #{job.inspect}" if @debug

where job is likely to be fairly large.

ruby 1.6.7 (2002-03-01) [sparc-solaris2.9]

It's rather irritating as it kills my program dead.  If I wrap puts

class IO
    alias :old_puts :puts
    def puts(*args)
       m = Mutex.new
       m.synchronise {
          old_puts args
       }
    end
end

Is that likely to help? Anything else I can do without breaking up
my data first, and having to reassemble it?

        Hugh
