The ToolTalk database server daemon performs three major functional duties:
It stores the ToolTalk session IDs of sessions with clients that have joined a file using the tt_file_join call.
It stores file-scoped messages that are queued because the
message disposition is TT_QUEUED
and a handler that can handle the message has not yet been started.
It stores ToolTalk objects specs.
It responds to requests into the ToolTalk filename mapping API.
