应对Common Lisp（SBCL）中的内存使用并将其最小化

I have a VPS with not very much memory (256Mb) which I am trying to use for Common Lisp development with SBCL+Hunchentoot to write some simple web-apps. A large amount of memory appears to be getting used without doing anything particularly complex, and after a while of serving pages it runs out of memory and either goes crazy using all swap or (if there is no swap) just dies.I have a VPS with not very much memory (256Mb)
