Transactional Memory

Should I just tell pthread-win32 users, "POSIX signals work without any trouble... just don't use more than N threads"?

That's not STM per the theory, is it? That's something very close to STM, but still requires workarounds and caveats. And w/ that attitude, Intel or AMD will never give us the hardware support that's needed.

Unless STM is simple and straightforward (which, even if the algorithm is complicated, it's _universal_, and so you won't have to roll your own everytime), then people will still mostly just _talk_ about STM rather than actually _using_ real STM, w/ the concomitant _realized_ benefits.
