And then I discovered Foreign.Concurrent, which allows one to associate a plain Haskell IO action to a pointer. The 'Foreign.Concurrent' name is a bit misleading to me; it seems this module is named so because it needs concurrency itself, rather than providing stuff for concurrency.
such finalizer cannot be run w/o concurrency support. you can find explanations in module docs. shortly speaking, finalizing occurs at time of GC and there is no way to run Haskell code at this moment except than using another Haskell thread -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
