Hello Matsumoto-san,

Thank you very much for clarifications! I tried to wrap around whole 
code with begin rescue block and I can catch ChildExited exception.  So 
now I have code like this:

require 'pty'

cmd = "/home3/cman/work/product/integrator/test/syb2/OCS-15_0/bin/isql 
-Uuser2 -Puser2 -Scman2"

begin

pipe_read, pipe_write, pid = PTY.spawn(cmd)

sleep 10

printf "TEST END\n"

rescue PTY::ChildExited => msg
    puts "Caught child exited exception!"
rescue => msg
    puts "Caught exception!"
rescue => e
    puts e.msg
    puts e.type
end


But now the problem is that ChildExited exception can occur at any 
moment after spawn and interrupt program in random place. In my test 
above I never get TEST END printed.

How can I handle this in right way?

Best regards,
Denis
