If mmap is available (try man mmap) you might want to check it out.
I maintain a LISP system on Suns et al and use mmap (not for
multiprocessing) and it gives you fast startup (no malloc then read
from heap file, just mmap) and automatuc state saving (no explicit
writing the heap to disk).  Good luck
