You can see several PHP CLI scripts all consuming far more memory than the
8M limit set in php.ini.



How is this possible.  My PHP scripts do not contain any code to allow
this.  They are daemons, with infinite loops, signal and error handling. 
Over a period of 5 days or so they consume more and more memory until the
server tilts.

Reproduce code:
---------------
Can't do this in 20 lines or less.

Expected result:
----------------
A maximum memory use of 8Meg - shouldn't even need this amount.
