   Is this 1024-byte buffer guaranteed to be large enough?

Good one.  I poked around in the Hurd source code, and couldn't really
figure out if it would be guaranteed (some places use a 2048 byte
buffer).  I think that this should be less than the block size of the
current file-system (according to [hurd]/ext2fs/inode.c and
[hurd]/ufs/inode.c).  Could some Hurd god comment on this and what
should/could be done?

It it has to be no more than block size of ext2fs, then it better be 4096. This is the maximum block size of ext2fs. (I think that Linux block layer can't map blocks larger than page size, which is 4K in i386. I'm not 100% sure though.)
