397	Need a tool to display IPC Event Channels	Gary Dixon	Eric Swenson	"It is sometimes necessary to display status information for the IPC event channels in-use by a given process in order to determine why the communication between two Multics processes is not functioning properly.

An Event Channel Table (ECT) is created in each active ring of a user process which invokes ipc_$create_event_channel (or one of the earlier channel creation subroutines) to request creation of a new event wait or event call channel for use in that ring.

A new tool is needed to:
- Display meters describing event channels in use by a given ring of a process.
- Display information about status of each event channel registered in that ring.

Ideally, the new tool would be able to display unhandled events recorded in the table on a particular event channel.  However, this may be difficult to do, since there is no particular format required for the event messages sent through event wait and event call channels.

Providing meters, and showing status of existing event channels would be a good start for such tool.
