I have not attempted to reproduce it, but with nice -n 19 the 'make bootstrap' 
didn't cause a repeat of the problem. It could have been a combination of 
things which were running at the same time. uClibc and gcc-4.1 don't get 
along very well, so I pointed the finger at that.

I think the majority of users build lfs/hlfs on a desktop system while running 
a gui/xorg. In these situations running 'make', and './configure', with 
'nice' is always a good idea, to keep the gui responsive.

I agree, but using a nice level controls unexpected problems. If we start 
using a lot of gcc options, like -DFORTIFY_SOURCE=2 -fstack-protector-all 
-Wformat=2 -Wsecurity -Wshadow -Werror -lmudflap, with maybe additional 
options like -fwhole-program -combine -fprofile-use, this starts using 
considerably more resources to compile and has a higher risk of getting out 
of control (while unstable).
