Good one...  In fact, this seems like such an obvious candidate
that hearing no objection, consider it added....  The "SYSTEM"
section of the "current limits" list seems like the best place to me:

> SYSTEM:

+   1140 processes can open one database for WRITE when
     IMAGE logging is enabled (user logging is still all CM).

Thanks, Brian......    Any other additions;  in any area ??
