I've never used afio but I think the problem is
that cdrecord expects iso images not arbitrary data.
Also your assuming that "find | afio | cdrecord" will
be able to keep the CD recorders buffers from emptying.
(Note forcing cdrecord to a low speed would help).

If you have the disk space I would let afio create
many files, which can be "converted" to iso format
using mkisofs. Then you can safely interate over
these with cdrecord.

If you don't have the disk space, and you
have a fast/idle/ disk/cpu then you could try
(completely off the top of my head):

find ~patrick | afio -o -b -K -b 2048 -s 614400x '!mkisofs /dev/stdin 
| cdrecord -eject speed=8 dev=0,0,0 -'
