Bigger   :p

On most of my systems, I've got
options MSGBUF_SIZE=163840
in the kernel config.  It's been carried around everywhere for many
years.  Where'd I get it from?  I'm not sure.  Before r56838 the
default was 8k, so I'd guess I doubled it to 16k, then hit a time when
it overflowed again and just lazily *10'd it.  Even back with 256 meg
systems, I didn't feel too bad about "wasting" 160k.
