The clog has somewhat re-formed - the full listing of lsof (filtered for unique files) for postmaster(s) on the database mount is here:
http://BillionUploads.com/ya9kjv78t9es/postmaster_files_sorted.csv.html

Consecutive commands were issued in a matter of minutes and differ slightly.

Some totals / aggregates:
df – /data 83 141 382 144
du – /data 29 170 365 801
lsof – /data 75 348 037 632
lsof – /data/base 74 975 969 280
lsof – /data/base (deleted) 53 769 936 896
lsof – /data/pg_xlog 369 098 752
lsof – /data/pg_xlog (deleted) 201 326 592
lsof – /data/global 2 965 504

It is clear that the server processes are keeping most of the files from being actually deleted.
