The clog has somewhat re-formed - the full listing of lsof (filtered for unique files) for postmaster(s) on the
databasemount 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.
