Db4 shared mem, ENOMEM on large import

Well, in response to the memory usage, the import of the tree I am doing
now only takes 103megs instead of 300megs of memory. Still getting the
failures in close_edit (more specifically in svn_fs_commit_txn when
calling svn_fs_retry_txn, on down into svn_fs_rep_contents_size).

After placing an abort just before the error return (and running under
gdb) I get this:

bottom:/usr/src/svn/repo/db# db4.0_stat -d strings
db_stat: Lock table is out of available locks
db_stat: open: strings: Cannot allocate memory
db_stat: Database handles open during environment close
db_stat: dbenv->close: Invalid argument

(lots more free objects).

So, somewhere we are running out of locks.
