Yes. I'd like to mention that I have been working on this myself during the past weeks and I have significant uncommitted changes in this area (I haven't looked at the symtab though, only at htab). I should be able to polish and benchmark my changes into a presentable state in the next month or so. Benchmarking takes a huge amount of time, but without it there's no point in making changes. Thanks
