Urgle. Isn't that a bit complex a technique for a simple
exchange of identities?

What is a "minor race condition"?
Do you mean (in the example) that a get() by the child thread may
return the initial 0 value, before the smart pointer actually
receives the thread object pointer? That may not be a minor problem,
such an error may result in caching the value on a multi-processor
system, so that all subsequent reads up to a synchronisation point
are wrong. Worse, the user may cache the value, which means
its permanently wrong. There's no such thing as a minor fault
in software. Its either correct, or its not. Would you allow
a 'minor race condition' in your heart pacemaker? :-)
