SBCL, as Steel Bank Common Lisp? Why would you run that on a server machine alongside Postgres? If I had to use SBLC
andPostgres, I'd put SBLC on a separate machine all its own, so that it couldn't corrupt Postgres or other servers that
hadto be reliable. 

Are you saying that if I bought a terrabyte of swap disk, SBLC would allocate a terrabyte of space?
