some heads up here

glibc-2.7 has sat in ~arch for much longer than i would have liked.  the only 
real issue holding it back is nscd.  i never use this thing myself, but on 
some arches (like ppc), it's known to eat your cpu like a dirty C-globbler 
(where C is short for CPU).  on other arches, it's known to just cream itself 
for fun and then promptly exit.

glibc-2.8 is supposed to be out soonish, and if nscd insists on continuing to 
be a pile, i'm afraid of having to just dump in a bunch of reverts.  nscd in 
glibc-2.6.1 seems to be generally OK.

Interesting - I saw nscd dying every so often with 2.6 (x86) but at least
for me that seems to have stopped since 2.7. Not sure what I'm doing wrong :)
On slower systems it certainly makes a noticeable difference.

In alpha we still have a bastard called 205099[1]. We need to track down 
the real problem there and fix it before we can mark 2.7 even ~alpha. 
Any help from toolchain ninjas is more than welcome. Thanks.

as noted, that needs to be fixed in the kernel.  working around it in glibc 
doesnt make the issue go away.  you could even call it a security vuln since 
any non-root user can take down the machine.
