pthread_rwlock_wrlock bug on amd64 with hoary hedgehog

my otherwise-painless upgrade to ubuntu’s hoary hedgehog release was marred by a bug in pthread_rwlock_wrlock() on amd64 that was fixed in the upstream glibc more than a year ago. ugh.

i wonder what the policy of ubuntu is with regard to fixing things like this. i really hope i don’t have to created a patched glibc myself.

on the bright side, the upgrade fixed the xserver configuration, so now it starts up and shows the pretty login screen. i logged in and it looked and sounded pretty.
