Heh, Chris, I remember a time, when you believed Euphoria's Memory Management
libraries we no where near what it needed to be.  So you wrote your own memory
routines.  Were they absolutely nesscary?

allocate_string()  = allocate(length(string)+1) poke(mem,string,length(string))

You created the library, was it absolutely nesscary, just on the off chance that
someone else would find it useful?  That it, as you said, "might be implemented"
?
