Yes, I've been discussing this w/ ad@, chs@, and riastradh@. I have a different approach that's almost ready to go, and will remove this separate "TID". The system call was not yet exposed in libc, so it's not a problem to pull it out. For various reasons, the ID must be limited to less than 32 bits. -- thorpej
