emerge pygtk results in 100% cpu usage by gcc on gtk.c for inadequate amount on time (tens of hours)
This is a lack of optimization in gcc due to what it needs a lot of RAM (400mb on my amd64 desktop) in order to compile gtk.c file. Build pygtk without
gcc eats ram like crazy during compilation
In order to keed down gcc appetite add the following to
--param ggc-min-expand=0 --param ggc-min-heapsize=<max_ram_gcc_is_allowed_to_take>. I chose 32768. Thanks to fanoush for this hint.

sys-fs/udev <= 141 (newer versions do not work with ancient 2.6.21 currently present on n8x0).
Many programs segfault on device with kernel Oops about v6_coherent_kern_range in dmesg
Your glibc is too new for diablo kernel. Either revert to <glibc-2.12 or apply commit 32cfb1 on top of diablo kernel.
/bin/sort hangs eating 100% cpu in QEMU
Currently this happens with >=coreutils-8.7. Use coreutils-8.5 instead.
