I have sent a patch to patches list enabling concurrent vacuums to
actually reclaim space while another long vacuum is running, i.e.
vacuums won't no longer block each other from removing deleted tuples.

see:

Could you perhaps test this patch as well, while you already have a
setup for testing parallel vacuums under big loads ?

Or perhaps you can share the setup/scripts/data so that I could run your
test myself as well ?
