I have no objections to this, but I absolutely object to this without
someone documenting and gathering consensus for consistent terminology
to be used between the kernel and glibc.

The relevant comment is here:
https://sourceware.org/bugzilla/show_bug.cgi?id=6399#c26

I'd like to see a glibc manual patch for the threads.texi file, which
can be completely linux-specific, to document gettid() and nomenclature.
It should talk about the nomenclature used to discuss these interfaces
and explain when it is or isn't valid to use a task id and with what 
functions.

For example does gettid *really* return a pid_t as considered by
userspace? It's not a full out process...

Cheers,
Carlos.
