I'm pretty sure that postgres hasn't run correctly under concurrency on
alpha for a long while. The lax cache coherency makes developing
concurrent code hard. Since there are rarely, if ever, people testing
postgres on alpha under load it's nigh on impossible to verify anything.
Having to adhere to a more complicated memory model than for any other
architecture isn't worth it, since there barely are users.
