So the file sticks around until the last time its closed, even though
no directory entry points to it. That's fine and dandy - that's the way
it should be, but if its true then how come somebody claimed that removing
the swap file crashed the system :-(

A mandatory lock would be pretty useless too if we're talking about
deleting the swap file. The mandatory lock will stop other processes
from opening the file and scribbling in our swap space, but will do
nothing to guard against deletion.
