I'm not entirely sure what is the purpose of detach as it's unique to N2184, 
but if it's only used to indicate "do not cancel on ~thread, please", there 
is no need for it to actually detach anything (invalidate the pthread_t 
handle), just set a "don't cancel" flag. The race you describe is then 
harmless.
