	This panic can be raised as a result of a call to one of a large

	number of functions. In general, the panic indicates an attempt to perform an

	operation on a thread or process by code running in another process - violating

	the security principle of process isolation. 

	There are exceptions to this general rule, for example, where the

	panic is raised because the calling process has insufficient capability. The

	precise reason is stated with the function(s). 

	-# The panic is raised on a call to the following function if the

	   process owning the thread performing the call is not the creator of the target

	   process or, if a handle is specified, the handle is not local.

	   - RProcess::SetParameter()

	   .

	-# The panic is raised on a call to the following functions if the

	   process owning the thread performing the call is not the same as the target

	   process.\n

	   - RProcess::Kill()

	   - RProcess::Terminate()

	   - RProcess::Panic()

	   - RProcess::SetJustInTime()

	   - RProcess::Resume()

	   - RThread::Kill()

	   - RThread::Terminate()

	   - RThread::Panic()

	   - RThread::Suspend()

	   - RThread::Resume()

	   - RThread::SetPriority()		 

	   - RThread::RequestComplete()

	   - RThread::RequestSignal()		 

	   .  

	   NOTE: the creator of a new process can kill or panic the new

	   process, change the new process priority and set the new process startup

	   parameters until the process is resumed (which the creator can also do). After

	   the new process has been resumed, then it becomes totally independent of its

	   creator, and any attempt to panic it, kill it etc will raise the KERN-EXEC 46

	   panic.

	-# The panic is raised on call to the following (Symbian partner

	   only) functions if the calling process does not have the PowerMgmt

	   capability (TCapability::ECapabilityPowerMgmt): 

	   - Power::PowerDown()

	   - Power::EnableWakeupEvents()

	   - Power::DisableWakeupEvents()

	   - Power::RequestWakeupEventNotification()

	   - Power::CancelWakeupEventNotification()

	   .

	-# The panic is raised on call to the following functions if the

	   calling process does not have the WriteDeviceData capability

       (TCapability::ECapabilityWriteDeviceData): 

	   - User::SetMachineConfiguration()

	   - User::SetHomeTime()

	   - User::SetUTCTime()

	   - User::SetUTCOffset()

	   - User::SetUTCTimeAndOffset()

	   .

	-# The panic is raised on call to the following function if the

	   calling process does not have the ReadDeviceData capability

	   - User::MachineConfiguration()
