Thread locked forever - Haskell - Acid State

I was worried that Acid State generates a lot of event files and breakpoints, and the custom "stepcut" told me that there is an implementation of an acid solution called createArchive that removes old events ... The problem is that when I use it I get this error:

<fileName.exe>: thread blocked indefinitely in an MVar operation

I think its corresponding w7 permissions, but when I run it under “admin”, I can’t see the console, but the event files still exist, so I assume that it does not work.

If I run the code through ghci, I do not get an error message, but it blocks the console, so I need CtrlC to continue to work.

Has anyone got this error?
