However, since there are two separate but related problems (AS-safe access 
to TLS variables, and ensuring allocation failure is reliably indicated by 
pthread_create or dlopen failure, rather than happening on access to a TLS 
variable when there is no good way to return a failure status), 
considering how the design for fixing one problem relates to the other 
problem (e.g. whether it introduces new code that would need to be removed 
again when fixing the other problem) is certainly relevant.
