I just performed a fresh checkout and managed to complete the entire 
build bootstrap process without problem (this one without specifying 
--jobs=2). The only thing different from last night was that I had 
upgraded TCI (an alternative to rxvt) to the latest beta but that 
shouldn't make a difference I think. I did this checkout before I saw 
the message I'm replying to now, don't know if I got the changes or not 
but it worked now. I will do a rebuild again and time it this time and 
then time another rebuild this time with --jobs=2 and see if both can 
complete successfully (and their respective times will be interesting 
for me to compare).
