callit means, do simply a /lib/libc.so.6 - call it from your
shell
like a real program to see, what's inside. I.e. on my SuSE10
it looks
like:

Hmmm - seems we need to check how they compile their glibc
and which
kernel-headers they use - I think Johannes is around and
might could
shade some light on that - maybe also on that resmgr stuff.

BTW: they use the following patch:
