It is indeed. It seems, though, that from Linux kernel 2.6.16 and glibc
2.4 on, things look better [1]. As a reference, Debian stable (not known
to adventure too far into the present ;-) is libc 2.7 on kernel 2.6.26.

Of course, "enterprise" GNU/Linux distros are said to be even more
conservative...
