it to recognise what ABI to use on amd64 (and possibly others) platform. Display PID and process name as a part of the 'info threads' output, TIDs alone are too confusing. Introduce new commmands 'tid <tid>' and 'proc <pid>' to accompany gdb's default 'thread <thread num>' to make the task of switching between different contexts easier.
