I support the addition of gettid (for use with those syscalls that take tids, and with appropriate documentation explaining the properties of tids) - and, generally, wrappers for all non-obsolescent architecture-independent Linux kernel syscalls, including ones that are very Linux-specific, except maybe for a few interfaces fundamentally inconsistent with glibc managing TLS etc. - they are, at least, no worse as a source of APIs than all the old BSD / SVID interfaces we have from when those were used as sources of APIs. -- Joseph S.
