It is a substantial size problem. There's also a performance issue - the gc has 
to read those tables and iterate in a non-trivial way. For example, if a struct 
has an embedded static array of pointers in it, you'll need a way to embed a 
loop in the gc scanner.

Compression has its own problem - performance.
