Oh, I see. I think I misunderstood the thread when I wandered into it and saw your answer, thinking that the question was whether variables set prior to t_suspend() can be used in the route invoked by t_continue(). I should read more carefully.

$var(x) keeps the value in the context of the process. t_continue() doesn't delegate route execution to other processes, it is executed in the context of same process. So, yes, it is also the same for rtimer processes. Actually, I can bet more for rtimer case, for evapi, I will need to double check, because the libev might create some extra threads around...
In other words, t_continue(tindex, tlabel, rtname) is like:
set_active_transaction(tindex, tlabel); route(rtname);
t_suspend() is the one that parks the transaction and you can resume processing it with t_continue() in other process, so if you set $var(x) before t_suspend(), don't expect proper value at t_continue().

Why is that, when the scope of $var() variables is, as I understand it, maintained only by a given SIP receiver thread?
Regardless, is this true only when async task workers are used, or is this also true with other mechanisms, like resuming suspended transactions in rtimer threads?
