Not really.  An upper bound would be the total size of the finished
indexes for one 10M-row table, but one would suppose that that's
overkill.  The leaf pages shouldn't have to stay in RAM to have
reasonable behavior --- the killer case is when upper-level tree
pages drop out.  Or that's what I'd expect anyway.

You could probably drop the inter-insert sleep for testing purposes,
if you want to experiment with several shared_buffers values quickly.
