+TargetMilestone: ---
+Summary: AppDomain.Unload() causing random crashes
+We have embedded Mono1.1.4 runtime running on Win32 platform. At various
+points of execution the host process calls into managed code to create a
+number of AppDomains using AppDomain.CreateDomain(). We then create
+MarshalByRef objects inside the AppDomains using
+AppDomain.CreateInstanceAndUnwrap() and call the objects methods to perform
+business operations.
+Once an app domain is no longer needed. We call AppDomain.Unload() to
+unload it and that seems to cause unpredictable crashes. The crashes may
+happen immediatly or until much later time. This leads us to suspect that
+it's GC related. Once we commented out all AppDomain.Unload() calls from
+our code, the program becomes stable. 
+This may be related to the earlier bug 55996.
