Greedy memory handling

I have a function that will *massively* benefit from having a 
persistent internal buffer it can re-use (and grow) from call to 
call, instead of re-allocating on every call.

What I don't want is either of:
1. To set a fixed limitation of size, if the user ends up making 
repeated calls to something larger to my fixed size.
2. For a single big call which will allocate a HUGE internal 
buffer that will consume all my memory.

What I need is some sort of lazy buffer. Basically, the 
allocation holds, but I don't want the to prevent the GC from 
collecting it if it deems it has gotten too big, or needs more 

Any idea on how to do something like that? Or literature?
