main-class-updater and other treads thread is stuck in native level IO (reading zip file, classloading), while it's not entirely clear what AWT is waiting for, it could be the project mutex read access, but I haven't found any other thread holding the write access for project mutex.

closings as wontfix, not clear what is supposed to be fixed, slow classloading IO is unfixable.
