TDPL, std.concurrency and OwnerFailed

[Alexandr Druzhinin]

Hello
I try to get known if daughter thread finished its work using 
OwnerFailed exception catching like TDPL says, but std.concurrency has 
no such symbol. So, something changed. Can somebody help me with this 
case - finding if a child thread finished/terminated?
I know about spawnLinked, but I want to get known about child state when 
sending, not receiving, because in the last case I don't know what of 
linked child threads is terminated.
