If you can afford the memory leak, you could probably afford the GC, no?

That section (only called at startup) doesn't seem to be 
performance-critical. It doesn't matter then if the GC does its thing 
during it.

And keep in mind that the GC only collects when an allocation is made. 
So if you never allocate with it again, you're basically in the same 
spot as now: allocated a few KB of memory that never get freed.
