@Araq I think Jester has fixed this issue since last time I checked on it, which is good. Prologue still has issues with ORC and threads, and they all still have leaking issues with asyncdispatch (asyncnet?), but I think things are looking better than they were before this release.
Jester doesn't leak because it avoids using asyncdispatch at all if it can (and any allocation that it can avoid for that matter). I'll withhold further judgements until I get the chance to re-test things on Nim 2.0.0, since it looks like things may be more stable than they used to be.
