All its standard io (i.e. stdin, stdout, stderr)  operations  will be redirected to the parent process through three streams  ( http://download.oracle.com/javase/6/docs/api/java/lang/Process.html#getOutputStream%28%29 getOutputStream(),   http://download.oracle.com/javase/6/docs/api/java/lang/Process.html#getInputStream%28%29 getInputStream(),   http://download.oracle.com/javase/6/docs/api/java/lang/Process.html#getErrorStream%28%29 getErrorStream()).  The parent process uses these streams to feed input to and get output  from the subprocess. Because some native platforms only provide  limited buffer size for standard input and output streams, failure  to promptly write the input stream or read the output stream of  the subprocess may cause the subprocess to block, and even deadlock."
Thanks, that is kind of what I was worried about regarding stdout/-err. I should have read the javadoc!
