TRACE API: trace identification

Hi,

im currently using genode's TRACE API to trace communication paths between multiple threads. For that to work properly I need to be able to map all corresponding trace events to each other. For example a RPC_CALL event to the corresponding RPC_DISPATCH event.

The problem is as follows. Since a trace event is logged _before_ the related action is executed, it is possible that a thread is preempted between those two actions. In that case I'm unable to do the mapping just using the information provided by the TRACE API or am I missing something?

Best regards,

Joscha
