I find that all versions of cdrecord after 1.6a1 do this, and this is due to a change in the software resulting in the FIFO being enabled by default, rather than needing to be explictly enabled, as in earlier versions. I see this on 2.2.2-RELEASE and 2.2.5-RELEASE - I'm using the worm device to drive a CW7502, Ricoh MP6200, Philips Omniwriter and a CDD 2000, BTW. Workaround (for cdrecord at least) is to set CDR_FIFOSIZE=0 in the environment or use '-fs=0' on the command-line, thus disabling the FIFO, apologies if this was already known (not subscribed to the SCSI list). It'd be nice if the SCSI driver were fixed 'tho - the whole idea of the FIFO is to enable on-the-fly mastering from NFS and other network filesystems.
