Sleep command

[Doug Easterbrook]

hi bas:

you didn't mention what kind of process -- but I saw server.       If its postgres that you are waiting for something to finish -- we have use listen/notify feature in the database.

basically, you tell postgres to notify you on changes to certain data.

then you get a callback when the change has occurred.


normally we use if to get told of changes to constants or setup files -- but you could use it for anything.

it avoids polling the database.


not sure if thats close to what you are doing --- but perhaps an option.
