-   (struct pthread) as an identifier that is unique at least among all
-   live threads in the process.  So we must synthesize some number to
-   use.  Conveniently, the 'pthread_t' value itself is already unique
-   in exactly this way (because it's the 'struct pthread' pointer).
-
-   The only wrinkle is that 'tid' is a (32-bit) 'int' and its high
-   (sign) bit is used for special purposes, so we must be absolutely
-   sure that we never use a pointer value with the high bit set.  (It
-   also cannot be zero, but zero is never a valid pointer anyway.)
-   The NaCl sandbox models for 32-bit machines limit the address space
-   to less than 3GB (in fact, to 1GB), so it's already impossible that
-   a valid pointer will have its high bit set.  But the NaCl x86-64
-   sandbox model allows a full 4GB of address space, so we cannot
-   assume that an arbitrary pointer value will not have the high bit
-   set.  Conveniently, there are always unused bits in the pointer
-   value for a 'struct pthread', because it is always aligned to at
-   least 32 bits and so the low bits are always zero.  Hence, we can
