It's a bug in the "rpc" module. Tunables must never be declared
'static' or the compiler can and will optimize them away (as you've
discovered). This is a fairly old but recurring issue -- see CRs
4354490 and 6734437.
It's something that code reviewers should catch.

Not a compiler bug, in my opinion. The compiler is doing exactly what
we told it to do ("assume nobody outside of this module can modify
this value unless someone here takes its address") ... just not what
we wanted.
