Gives me a headache, too, especially once it vectors off into _the glibc nss code. These routines (gethostbyname2r is the _likely suspect, _gethostbyaddrr and getservbynamer might also get called) do have paths that could twiddle a glibc internal lock so it's not impossible there's an issue here, although at something less than a term-paper-depth look it doesn't SEEM like it should ever be able to block for very long.

Are there any tools for observing the locking calls made? Maybe just an strace would help.
