I think polling is OK. On modern computers polling sdsocket with 0.1s or 0.01s
interval should produce no human noticeable delay. ymmv.

What is the best mechanism for sending aynchronous external events to the J

In Windows, DDE has been decomitted, but I can still use sockets. When I
get a new socket event, socket_handler is called. Is this also true in
Linux? Or must I poll?
The problem with polling is:
(A) The target of this application is J developers (who will be using
the
session manager for their own purposes). So I can't block, pause
or slow (for a human-appreciable amount of time) the IJX window
or interfere with other running programs. So I can't poll too
frequently.
(B) The effect of the event is GUI and should be noticeable immediately
(again, in human terms), so I can't pool too infrequently.
What are my options? Can I intercept SIGs in the J session manager? I
looked into jbreak, but it looks like that's treated as a special case in
the binary, so I can't leverage the mechanism.
