select with signals. If you could give me more hints about what could
happen, I would be happy to discuss possible solutions with you.
If I could offer one solution to the users and make everyone happy, I
would do it. Unfortunately, the poll function call is not available
several systems.
LuaSocket uses non-blocking I/O and makes heavy use of the select
function to avoid busy waiting. Even if I offered support for the poll
function, that wouldn't get rid of your problem unless I changed the
internal usage of select in LuaSocket too.
Maybe there is another fast way of checking the time. How about passing
this responsibility to the clients? I know it is not as safe as having
the server handle it, but it might work well enough.
Regards,
Diego.
