[developers] LKB images on 32-bit FC6 machine

[Ben Waldron]

Have you tried playing with the following "black magic" parameters (in 
~/.clinit.cl)? Nudge the numbers a little and memory allocation problems 
such as you are having below tend to disappear -- for a while, at least...

(setf (sys::gsgc-parameter :generation-spread) 20)
(sys:resize-areas :verbose t :new 128000000 :old 64000000)
