I think so.  The bug is in the Berkeley DB v 1.65 btree code in the
base system -- the BDB v1.65 *hash* implementation is not affected.
About the only downside is that the various portsdb or portupgrade
operations might take a few milliseconds longer.  There have been
three or so patches of various degrees of efficacy put up for testing
on freebsd-current at ... by Jun Kuriyama (the latest being a port of
what the netbsd folks did to fix this problem, which is probably going
to do the trick).  Chances are this is going to be fixed in 6-CURRENT
fairly soon, and MFC'd to RELENG_5, RELENG_4 and maybe even
RELENG_4_10 within a few days of that.  Once you've updated to a
patched base system, you can revert to normal operation simply by not
setting that environment variable any more.

	Cheers,
