Yes, but have you actually tried to upgrade a glibc installation in-situ 
(i.e. on the OS you're currently booted into)?  I remember quite clearly 
the effects that had when I accidentally replaced my host's glibc with 
an LFS compiled version...it's not pretty, and yes, they were the same 
version (2.3.4).  This may well have been caused by the host having 
vendor-specific patches, or being compiled with a different version of 
gcc, but the experience has definitely put me off ever trying to do such 
a thing on purpose!
