I modified G_recreate_command to use a buffer of ARG_MAX size and to
make sure the buffer isn't overrun.  Still, I get a sigpipe from the X
server and it exits.  I traced it on the client side to the point in
Rasterlib where flushout() is called by _send_char.  Is there some
problem here if the buffer is flushed, but the communication is not
complete?
