well, this java's notion of ``memory is running low'' actually
is a bit complicated (and interesting), 
please try see the function computeSoftRefThreshold(void) of 
j2sdk1.3.1/src/share/javavm/runtime/gc.c
I was amazed with this (and struck again how
inaccurate my interpretation of ``documents/specs'' are :p)
