from the fakeroot man page: "Every command executed within fakeroot needs to be linked to the same version of the C library as fakeroot itself." glibc was recently updated, and I have FEATURES=fakeroot set, which may explain why I am suddenly unable to complete emerge -eav world (random hangs without cpu usage). testing now with FEATURES=-fakeroot set (another possible cause for the hangs might be bug 487558) given the manpage, my suggestion would be that * either the sys-libs/glibc ebuild outputs a fat warning on update if FEATURES=fakeroot is set * or that portage detects a glibc update and warns

I'm closing the bug, reopen if you still want to act on it.
