RE: XSH/XRAT conflict over cancellation points

The real defect here is that POSIX still doesn't defer to 
ISO/IEC 14882. Thread cleanup handlers shall be defined 
semantically equivalent to dismissible C++ "scope guards" 
of the local scopes formed by pthread_cleanup_push/pop() 
and thread exit/cancel shall be defined semantically 
equivalent to unspecified C++ exception (POSIX.C++ profile 
shall specify them, of course). No brain-damaged volatiles 
needed.
