My machine appears to be much faster than yours, however, I am still able to reproduce this in my testing.

I tried with these commands:

scons -c
time scons

On 730ccaa (the commit before PR #1162):

real    0m35.237s
user    13m15.284s
sys     2m19.489s

On 96565e1 (current master):

real    1m55.579s
user    51m56.977s
sys     3m50.841s

My guess is that this is from the changes to type_info.hpp which ends up getting included everywhere. I'm not sure how to improve this...
