Set blocking on stdout so it will flush all data when writing to a pipe. Currently, large JSON results piped to x2j can result in an output buffer larger than 64k, and the remainder does not get flushed when the process exits. This causes a problem where piping the output of this command for large files currently results in truncated output. See also nodejs/node#6297 for notes on the process exit and stdout buffer flushing.
