   If I'm not mistaken, ElectricFence will never give the same piece 
   of memory to an app if the app does a malloc()/free()/malloc(). Meaning,
   an app that uses a bounded amount of memory without efence will use
   an ever increasing amount of memory with efence. 

i believe this is not true.  it *is* a possible way to run
efence but the default it isn't.
