I believe this is area is finalizing the session ( closing the session )..

sometimes this can take longer than the actual burn itself ..

cdrecord does im happy to say do it properly ...

Have you tried ..

1.    trying a newer version of cdrecord
2.    see if there are any reports of Firmware issues if so upgrade it

I have a cdd2600 philips scsi device that does'nt play nice at all and only
cdrecord can kick it where it hurts to make it behave or so to speak.. I did
have to Firmware upgrade both my Adaptec Scsi card and the burner ..

cdrecord still complains slightly about the scsi card and its throughput

but it burns quite nicely.
