An event was canceled while a blocked thread or fiber was waiting on it.
An unknown catastrophic failure occurred. When a method returns E_FAIL, the CLR is no longer usable within the process. Subsequent calls to hosting methods return HOST_E_CLRNOTAVAILABLE.
SwitchIn was called without an earlier call to ICLRTask::SwitchOut Method.
The threadHandle parameter represents a handle to the operating system thread on which the task represented by the current ICLRTask instance has been scheduled. If impersonation has occurred on this thread, you must call IHostSecurityManager::RevertToSelf before switching in the task.
