The problem is really that libthr (and all other necessary
libraries) need to have their versions bumped.  It's not
just thr_getscheduler.  There were networking changes added
that required the libc version bump.  If there had not been
a version bump to libc, adding thr_getscheduler() and friends
to libc.so.6 would not have caused you or anyone else any
grief.  We add functions and system calls all the time to
libc without any problems.  It is only when library
versions are bumped that cause problems.
