Us. We're keeping the FS object open, which with the BDB back end means
holding open the database, and thus its files. With the FSFS back end,
rev files are opened as needed and then closed again, so merely having
an open FS object doesn't mean having open files.

(As best I understand the situation.)

A better reason to make sure we don't hold open many RA sessions at a
time is that an RA session may represent an ssh process to the server,
which is consuming server resources.
