sample solution to explain problem

User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.2)
Gecko/20100121 Mandriva Linux/1.9.2-69.1mib2010.0 (2010.0) Firefox/3.6

I used an AssemblyLoader class loaded in a different AppDomain to load a plugin
assembly and create a plugin class calling CreateInstance method of
AssemblyLoader class.
Instance of plugin class implement ISharedClass so i call a method Exec()
contained into interface and implemented in plugin class, after unload
AppDomain created and i used also GC.Collect() + GC.WaitForPendingFinalizers().

i put this steps in a loop and after some times.... freeze

in my real application my plugin is more complex and i have a freeze after
first or second appdomain.unload

i haven't this problem on mswindows 

i saw this problem already in prev. Mono releases

Reproducible: Always

Steps to Reproduce:
1. launch mono --debug LoadAssemblyConsoleApp.exe
2.
3.
Actual Results:  
freeze of application

Expected Results:  
application terminate correctlly
