You might want to order these in the order of "least resistance", i.e., things which are obvious and have no downsides, we can get in even before the more controversial stuff - so that only the controversial stuff remains in the queue for long, instead of having 20 uncommitted patches, we'll have just 3 ;-) If you can, please search the mailing list archives for my old comments on some of Benoit's patches, on some of these I had comments which might still be relevant. If you can figure out ways to make the changes harmless to non-Go workloads, that would be great (e.g., one thing that would be nice to figure out is how to not allocate a systemcall stack for every single thread in the system). I seem to remember there were some important TLS-related patches from Benoit, on the order of when the TLS variables were allocated or initialized or something, which was rather ugly. Don't you still need those patches? It's been a long time now, so I don't remember the details, unfortunately.
