beforeGarbageCollection

[Andrei Alexandrescu]

I'm thinking of a feature that would improve the memory footprint of D 
programs. Say druntime provided a function:

void beforeGarbageCollection(void delegate() callMe);

The runtime would guarantee that callMe gets called before any 
collection. That would allow modules to clean up caches (e.g. free 
lists) to improve their memory profile.

Any thoughts, please share.
