close_out would trigger a Sys_error("Broken pipe") exception now that we ignore the SIGPIPE signal. Instead of catching and handling it, we simply use close_out_noerr which ignores all errors

close_out_noerr(cmd_in);

let cmd_out_descr = Unix.descr_of_in_channel(cmd_out);
let cmd_err_descr = Unix.descr_of_in_channel(cmd_err);
