I'm currently working on the forcing GC cleanup mechanism for my web 
server. I would like to add, that post GC disabled it can be forced to 
do a cleanup.

But I would go a step further, do a force minimize of memory back to the 
OS and reserve e.g. 32mb. Really what would be nice is a, reserveMax 
function that and anything else is free'd back to the OS.

The reserve, means that even if you are sloppy and end up using the GC 
in critical code, it won't matter. The memory is already allocated. 
Cleaning up can happen during non critical times. After all, if you are 
using more then e.g. 32mb in critical code, you are doing something wrong.
