kernel / libc_r (KDE) breakage - UPDATING note?

Has anyone else experienced problems with kernels from today's -CURRENT
causing problems with libc_r from last week?  I just cvsup'd, and the new
kernels I build all cause KDE to hang in interesting ways before it can
complete its startup.  Jumping back to a kernel from last week makes this
problem disappear.

Is there an entry in UPDATING telling me to update libc_r that I missed,
or is libc_r just plain broken?

Thanks,
