Too many open files, again

Hi Toby,

There does seem to be a problem with too many open files under Mckoi 1.0.2. I
have tried this on three different JVMs (IBM, BEA JRockit and Sun) on
different Linux boxes. The problem seems to occur only during the backup
process using the system_make_backup call -- I have not seen it show up in
any other circumstance. I have this backup enabled every day, but it only
seems to happen after a week or so of the application being up and running.

The stack trace is below. It's the same message I receive on all the
occasions that it has failed. I would appreciate any ideas. Thanks.
