Putting a lot of data into a session variable is NOT a memory leak. It is
just bad design, pure and simple. A memory leak is when you (in other
languages, as CF is based on Java which is meant to prevent memory leaks)
allocate memory for a variable and then don't dealocate it. Something like
this:
char *c;
for (int x=1;x<1000;x++)
c=malloc(1000*sizeof(char));
This allocates 1k array 1000 times and doesn't free the memory. The memory
becomes lost and inaccessible, and is therefore a memory leak.
