I'm betting that Postgres doesn't think there's any TAS support on the
MIPS machine. This may actually be true depending on what model of
MIPS it is --- IIRC, there were no userland synchronization instructions
in MIPS-1. If it's MIPS-2 architecture, then the problem is we don't
know what to test for.

What's the signal you're getting?
