[ambrus]: in the loop, and I'm not sure if that's ok for AnyEvent. Also, it's not clear if a Timer or File object you free really is garbage collected, i.e. that Prima doesn't keep some references to it, but I hope so.
[Corion]: choroba: No, I don't remember that story, but yes, it matches my experience ;))
[ambrus]: Hopefull the object isn't kept alive, the events are processed immediately, but you'd have to read a lot of source code to be sure about that.
[Corion]: ambrus: I think both of AnyEvent and Prima are pretty tight in their memory management because they both are cooperative multitasking and (I think) both use the Perl memory management for managing things
[Corion]: ambrus: And for Windows, I don't think that Prima knows if there still are messages queued for an object (in the Windows message loop). Finding that out would take lots of effort for little gain
[ambrus]: And even if this works, I'm still not sure you can't get double timeouts from a Timer.
[ambrus]: Corion: well Prima::Object says something like that the cleanup method will send an onDestory message and that you can't get more messages after cleanup, or something.
[Corion]: ambrus: Yeah - I don't think the deep source dive will be necessary if things are implemented as simple as they could be :)) And hopefully I won't need (more) timely object destruction. I can update the screen at 60Hz and hopefully even do HTTP ...
[Corion]: ... transfers in the background. Now that I think about it, this maybe even means that I can run the OpenGL filters on Youtube input :)
[ambrus]: Corion: I mentioned that the unix event loop of Prima always wakes up at least once every 0.2 seconds. Have you found out whether the win32 event loop of Prima does that too?
