Invokes the given command synchronously on the current connection. (This
means that parallel commands and operations cannot be executed when this
method is used.) This will return <tt>nil</tt> if the method could not be
executed. If the command is successfully invoked, and a block is given, the
block is then invoked with the input, output, and error streams of the
command as parameters, and the channel is closed as soon as the block
terminates. If a block is not given, the input, output, and error channels
are returned and the process <b>might</b> not terminate until the session
itself terminates.
