[Jax.PM] references

For all practical purposes it goes away - depending upon context.  If your 
programs and data behave like the 80's version of a TSR - then all bets are 
off...

Under mod_perl within Apache 1.x you could access the shared memory (all data is 
addressiable by all apache programs - which includes mod_perl, mod_php, etc.)

The age old preferred method is to write out your data structures to disk and 
re-read them upon the next program invocation.

Generally speaking references are meaningless between and among programs -- 
there are various security and program structure reasons for this.

What I guess I should say is - what you describe would allow ANY program to 
access your data if the references stayed in memory AFTER your program exited. 
That would be a security violation - whether implied or enforced - one that no 
sane programmer would want.


Not that I am claiming to be sane...
