   - Should we meet more often/longer?  (see separate email)

     Abi would prefer not to extend the meeting.  Abi would prefer creating sub-committees
     to handle the meat of the problems.  Chuck is okay with any of the proposals.
     Decided for now that each person responsible for a major topic will try to form
     informal working groups so that more progress can be made outside of our normal meeting.

   - Item 1456 Clarify, circumscribe restrictions on use of DPI context utilities
     Ralph had found another issue when reviewing the changes which were passed for this
     item.  We should vote again to accept his new change.
     Abi/Chuck.  PASSED (unanimous)

   - State of the Mantis Items.  Any issues?
     Chas described the changes to the mantis items.  Asked that if anyone finds mistakes
     to please let him know.

   - Declare Item 2152 as a duplicate of Item 2097?
     This is an SV-BC item.  They need to close it out.

   - Update PASSED items to reflect draft 4 (i.e. 1837)
     Champions are meeting tomorrow.  Please update proposals to reflect draft 4.
     Champions had a backlog, not sure now.  Meeting every 2 or 3 weeks.
     Will be reviewing 1751 1942 1570 1367 tomorrow.

   - Move Item 1503 to SV-AC?
     Chas asked that the SV-AC send the proposal back when they are done so we can
     review it.
     Chuck moves to send to SV-AC.  Bassam seconds.  ACCEPTED (unanimous)

   - DPI changes for disabling tasks consuming time
     Section 26-8 in 1800-2005.  This has a protocol for disabling an exported task.
     It must return a value of one.  In the case of an imported task has been disabled
     it can detect that.  They are supposed to be transparent to the user that they
     are calling a foreign task.  Since SystemVerilog tasks don't return a value,
     the return value is not needed.  Chas recommended that Amit talk with Ralph and
     Doug Warmke.

   - vpiValid discussion
     Need a lightweight object.  The lifetime and having a value should go with the
     type of the object.  Creating different kinds of objects depending on whether or
     not they are static or have values.  Long discussion on what we should do with
     this.  Abi is getting towards a proposal.  There is still a lot of disagreement
     or misunderstanding to be worked out though.

   - No more new business.


5.  Reviewed items with proposals
