Increasing the RDLINE_BUF_SIZE size will also increase application memory usage.
However, that memory increase was required, because application could not fit 
it's command line into the default buffer.

Applications that can run with the default RDLINE_BUF_SIZE are not affected by 
that patch.

Regards,
Gregory
