[CentOS] why glibc-profile package get obsolete?

Hi,

 Any one know why the glibc-profile is obsoleted on
centos 5 (glibc 2.5)? I've checked the glibc.spec file
and find that the --disable-profile option is enabled
in the configuration command. 

 So how the original profiling functions are
implemented on glibc 2.5? Is there a new way to do the
same/similar thing? 

 Thanks a lot.
